This article examines the existing software applications for electronic circuit prototyping that can help evaluate the operation of the entire circuit based on specified parameters and find the best options. Using the TAC application and the Arduino library components, projects and instructions for creating and testing electronic circuits were developed. The resulting application was tested for capabilities and efficiency. The interface design and settings were also assessed to determine whether they simulate real conditions. The functionality of TAC application made it possible to generate alternate circuits. The results of software testing showed that using the application speeds up the learning process significantly when compared to traditional methods and helps eliminate problems that may emerge when designing and assembling circuits. The application may be useful in designing complex electronic circuits and developing teaching aids for students in technical fields.

Streszczenie:

This paper presents a maximum power point tracking (MPPT) interface circuit for low-voltage DC-type energy harvesting sources such as light and thermal energy. Most energy harvesting systems used in miniature-sized sensor systems require start-up circuits because the output voltages of small-sized energy transducers are very low and not enough to directly power electronic systems. The proposed interface circuit is driven directly by the low output voltages of small size energy transducers, eliminating the need for complex start-up circuitry. A simple MPPT controller with the fractional open-circuit voltage (FOCV) method is designed and fabricated in a 65-nm complementary metal oxide semiconductor (CMOS) process. Measurement results show that the designed circuit can track the MPP voltage even in the presence of the open-circuit voltage fluctuations and can operate properly at operating voltages as low as 0.3 V. The interface circuit achieves a peak power efficiency of 97.1% and an MPPT accuracy of over 98.3%.

Piezoelectric energy harvesting has gained significant attention for powering small-scale electronic devices by converting mechanical vibrations into electrical energy. However, the electrical interface plays a crucial role in maximizing power transfer efficiency. This paper explores optimized circuit topologies, particularly the use of inductors to mitigate capacitive impedance effects and enhance power output. A comparative analysis of Simple Resistive Load (SRL), Inductive Load (IL), and AC-DC converter circuits is conducted, both numerically and experimentally. Results indicate that inductive circuits significantly improve power output by reducing the negative reactance of piezoelectric harvesters. The findings contribute to the development of more efficient self-powered systems for wireless sensors and low-energy electronics.

Streszczenie:

In piezoelectric energy harvesting systems, energy harvesting circuits are the interface between piezoelectric devices and electrical loads. The conventional view of this interface is based on the concept of impedance matching. In fact, in the power supply circuit can also apply as an electrical boundary conditions, such as voltage and charge, to piezoelectric devices for each energy conversion cycle. The major drawback of piezoelectric power harvesting have low-power relationships in systems within (in the range of μW to mW), then system also have significantly reduced any potential losses in circuits that make up the EH system, whereas other condition into careful selection of circuits and components can enhanced the energy harvesting performance and electricity consumption. In the study of energy harvesting systems, it is an energy harvesting system approach that using active and passive electronic circuit to control voltage and or charge on piezoelectric devices as proposed and review to mechanical inputs for optimized energy conversion. Several factors in the practical limitation of active and passive energy consumption, due to device limitations and the power efficiency of electronic circuits, will be introduced and have played an important role into to enhance optimum and increase efficiency of energy harvesting system.

The acquisition of high-voltage signals from sensors and actuators in an internal-combustion engine is often required for diagnostic purposes or in the case of conversion to alternative fuels, such as hydrogen, natural gas, or biogas. The integration of electronic interfaces and acquisition circuits in a single device provides benefits in terms of component-count reduction and performance. Nonetheless, the high voltage level of the involved signals makes on-chip design challenging. Additionally, the circuits should be compatible with the CMOS technology, with limited use of high-voltage options and a minimum number of off-chip components. This paper describes the design and the implementation in 350 nm CMOS technology of electronic interfaces and acquisition circuits for typical high-voltage signals of automotive context. In particular, a novel co-design of dedicated voltage clamps with electro-static discharge (ESD) protections is described. The proposed circuits require only a single off-chip resistor, and they are suitable for the acquisition of signals with peak voltages up to 400 V. The measured performance of the silicon prototypes, in the [−40 °C, +125 °C] temperature range, make the proposed electronic interfaces suitable for the automotive domain.

Streszczenie:

Several on-body sensing and communication applications use electrodes in contact with the human body. Body–electrode interfaces in these cases act as a transducer, converting ionic current in the body to electronic current in the sensing and communication circuits and vice versa. An ideal body–electrode interface should have the characteristics of an electrical short, i.e., the transfer of ionic currents and electronic currents across the interface should happen without any hindrance. However, practical body–electrode interfaces often have definite impedances and potentials that hinder the free flow of currents, affecting the application’s performance. Minimizing the impact of body–electrode interfaces on the application’s performance requires one to understand the physics of such interfaces, how it distorts the signals passing through it, and how the interface-induced signal degradations affect the applications. Our work deals with reviewing these elements in the context of biopotential sensing and human body communication.

This work presents the design of a discrete second-generation voltage conveyor (VCII) and its capability to be used as electronic interface for silicon photomultipliers. The design addressed here exploits directly at the transistor level, with commercial components, the proposed interface; the obtained performance is valuable considering both the discrete elements and the application. The architecture adopted here realizes a transimpedance amplifier that is also able to drive very high input impedance, as usually requested by photons detection. Schematic and circuital design of the discrete second-generation voltage conveyor is presented and discussed. The complete circuit interface requires a bias current of 20 mA with a dual 5V supply voltage; it has a useful bandwidth of about 106 MHz, and considering also the reduced dimensions, it is a good candidate to be used in portable applications without the need of high-cost dedicated integrated circuits.

In this work, an interface circuit applied to resistive gas or chemical sensors is proposed. The interface circuit includes a detection front-end, a single-end to differential circuit, a successive approximation analog-to-digital converter (SAR ADC), and some reference auxiliary circuits. In detection front-end circuits, mirrored currents in a current mirror usually differ by several orders of magnitude. In order to ensure that the current mirror can be copied accurately, this work uses a negative feedback structure consisting of an operational amplifier and an NMOS tube to ensure that the VDS of the current mirroring tube remains consistent. Simulation results show that the replication error of the current mirror is 0.015%. The proposed interface circuit has a detection range of 10 Ω to 1 GΩ with a relative error of 0.55%. The current multiplication or divided technique allows the interface circuit to have a high sampling frequency of up to 10 kHz. The proposed circuit is based on a 180 nm CMOS process with a chip area of 0.308 mm2 (723 μm ∗ 426 μm). The power consumption of the whole interface circuit is 3.66 mW when the power supply voltage is 1.8 V.

Abstract The paper describes a new electronic conditioning circuit based on the current-processing technique for accurate and reliable humidity measurement, without post-processing requirements. Pseudobrookite nanocrystalline (Fe2TiO5) thick film was used as capacitive humidity transducer in the proposed design. The interface integrated circuit was realized in TSMC 0.18 μm CMOS technology, but commercial devices were used for practical realization. The sensing principle of the sensor was obtained by converting the information on environment humidity into a frequency variable square-wave electric current signal. The proposed solution features high linearity, insensitivity to temperature, as well as low power consumption. The sensor has a linear function with relative humidity in the range of Relative Humidity (RH) 30-90 %, error below 1.5 %, and sensitivity 8.3 x 1014 Hz/F evaluated over the full range of changes. A fast recovery without the need of any refreshing methods was observed with a change in RH. The total power dissipation of readout circuitry was 1 mW.

Streszczenie:

Direct interface circuits (DICs) avoid the need for signal conditioning circuits and analog-to-digital converters (ADCs) to obtain digital measurements of resistive sensors using only a few passive elements. However, such simple hardware can lead to quantization errors when measuring small resistance values as well as high measurement times and uncertainties for high resistances. Different solutions to some of these problems have been presented in the literature over recent years, although the increased uncertainty in measurements at higher resistance values is a problem that has remained unaddressed. This article presents an economical hardware solution that only requires an extra capacitor to reduce this problem. The circuit is implemented with a field-programmable gate array (FPGA) as a programmable digital device. The new proposal significantly reduces the uncertainty in the time measurements. As a result, the high resistance errors decreased by up to 90%. The circuit requires three capacitor discharge cycles, as is needed in a classic DIC. Therefore, the time to estimate resistance increases slightly, between 2.7% and 4.6%.

Streszczenie:

MEMS devices are typically used in subsystems comprising the MEMS component and the infrastructure required to support it. This infrastructure – signal processing, communication interface, power supply, and system packaging – often determines the size and cost of the subsystem. This paper describes a new approach to fabrication of highly miniaturized electronic circuitry and packaging that is well-suited to interfacing and support of MEMS components. The fabrication process utilizes nanoparticle silver conductors to connect miniature embedded surface-mount components. Interconnect conductors are produced by filling laser-ablated channels with nanoparticle silver pastes that cure at low temperatures. This laser-based approach allows production of very fine line interconnect structures (< 10 micron trace widths), which simplifies conductor routing and reduces layer count. Avoiding subtractive copper processes significantly reduces capital equipment and facilities costs and minimizes waste streams. After interconnection, the component assembly is encapsulated in a thermally conductive epoxy to produce a robust, stackable electronic module. Techniques also have been developed for stacking and interconnection of these circuit modules to form 3D electronic systems of nearly arbitrary form factor. All fabrication processes are CAD/CAM controlled, providing fast adaptability to design change and a smooth transition to production in both small and large volumes. The new fabrication technology has been applied to the challenge of miniaturization of wireless sensor nodes with the goal of constructing complete nodes of sugar-cube size (including an advanced battery). Node form factor can be easily adapted to specific applications.

The characterization of ultra-low power (ULP) fully-differential/balanced amplifiers and active filters is challenging due to the incompatibility with the classical single-ended (SE) and 50 Ω impedance equipment. Interface circuits between the device under test (DUT) and the equipment are needed to perform the signal conversion and to work as voltage buffers. In this work, we propose a generic test circuits to be used in the characterization of ULP and ultra-low voltage (ULV) analog circuits. The test board includes balun transformers to the signal conversion, a high input impedance and low capacitance output driver and voltage regulators to provide the target DUT supply voltage. The characterization of the proposed PCB demonstrates a bandwidth of 30 MHz, output driver input impedance of 5 MΩ with 2.5 pF capacitance and low input-referred noise. The proposed circuit was applied to the electrical characterization of two fully-differential ULV and ULP analog integrated circuits.

Piezoelectric Vibration converters are nowadays gaining importance for supplying low-powered sensor nodes and wearable electronic devices. Energy management interfaces are thereby needed to ensure voltage compatibility between the harvester element and the electric load. To improve power extraction ability, resonant interfaces such as Parallel Synchronized Switch Harvesting on Inductor (P-SSHI) have been proposed. The main challenges for designing this type of energy management circuits are to realise self-powered solutions and increase the energy efficiency and adaptability of the interface for low-power operation modes corresponding to low frequencies and irregular vibration mechanical energy sources. In this work, a novel Self-Powered (SP P-SSHI) energy management circuit is proposed which is able to harvest energy from piezoelectric converters at low frequencies and irregular chock like footstep input excitations. It has a good power extraction ability and is adaptable for different storage capacitors and loads. As a proof of concept, a piezoelectric shoe insole with six integrated parallel piezoelectric sensors (PEts) was designed and implemented to validate the performance of the energy management interface circuit. Under a vibration excitation of 1 Hz corresponding to a (moderate walking speed), the maximum reached efficiency and power of the proposed interface is 83.02% and 3.6 mW respectively for the designed insole, a 10 kΩ resistive load and a 10 μF storage capacitor. The enhanced SP-PSSHI circuit was validated to charge a 10 μF capacitor to 6 V in 3.94 s and a 1 mF capacitor to 3.2 V in 27.64 s. The proposed energy management interface has a cold start-up ability and was also validated to charge a (65 mAh, 3.1 V) maganese dioxide coin cell Lithium battery (ML 2032), demonstrating the ability of the proposed wearable piezoelectric energy harvesting system to provide an autonomous power supply for wearable wireless sensors.

As the PCIe 6.0 specification places higher requirements on signal integrity and transmission latency, it becomes especially important to improve signal transmission performance at the physical layer of the transceiver interface. Retimer circuits are a key component of high-speed serial interfaces, and their delay and jitter size directly affect the overall performance of PCIe. For the typical retimer circuit with large-latency and low-jitter performance, this paper proposes a low-latency and low-jitter Retimer circuit based on CDR + PLL architecture for PCIe 6.0, using a jitter-canceling filter circuit to eliminate the frequency difference between the retiming clock and data, reduce the retiming clock jitter, and improve the quality of Retimer output data. The data are sampled using the retiming clock and then output, avoiding the problem of large penetration latency of typical retimer circuits. The circuit is designed using the CMOS 28 nm process. Simulation results show that when 112 Gbps PAM4 data are input to the retimer circuit, the Retimer penetration latency is 27.3 ps, which is 83.5% lower than the typical Retimer structure; the output jitter data are 741 fs, a 31.4% reduction compared to the typical retimer structure.

Metal/polymer composites are used in numerous technical applications. For example, polymer coatings on metal surfaces are used for corrosion protection, metal films on polymers inhibit static buildup, and polymers between two metals can serve as a “glue” for connecting materials that cannot be welded. Polymer/metal composites also play an important role in modern electronics. In condensers, polymers serve as insulating layers between metallic leads and are used to encapsulate entire electronic circuits. In all circumstances, interfaces are formed between the two different materials, and since the chemistry and structure change abruptly, interfacial failure is frequently observed.The cause of failure may just be mechanical (e.g., shrinkage of the polymer during curing), or the interface stability may be degraded by attack of aggressive species, resulting in delamination. More specifically, loss of adhesion is directly caused by interfacial electrochemical reactions that nucleate at a defect and progress into intact regions of the interface. This occurs for encapsulated electronic parts in humid atmospheres as well as for lacquers on automotive parts.Thus the investigation of corrosion reactions at a buried interface is an important area of research, but it is made very difficult by the fact that most electrochemical methods do not give information on localized reaction kinetics at a buried (metal/polymer) interface. This situation has changed with the invention and development of the scanning Kelvin probe (SKP). This method allows, for the first time, local analysis of reactions occurring at a buried metal/polymer interface. Based on the results obtained with the SKP, a detailed reaction model for the delamination process has been developed. This understanding has led to the development of new approaches that protect the interface from delamination. The idea is to chemically modify the interface using Afunctional molecules that promote adhesion between metal and polymer surfaces.

In thin‐film transistors (TFTs), issues such as interface states may lead to unstable device performance and complex physical phenomena, such as frequency dispersion effects. This paper establishes a three‐terminal TFT compact model capable of replicating capacitance dispersion phenomena and directly applying to SPICE circuit simulations. The model decomposes the transistor's capacitance frequency response into the superposition of responses from different electronic states. The different electronic states are emulated by parallel branches, each composed of voltage‐dependent capacitance and resistance connected in series. The Powell algorithm is employed to achieve automatic parameter optimization. The model is generic for TFTs and successfully replicates capacitance dispersion phenomena in carbon nanotube (CNT) and indium‐gallium‐zinc‐oxide (IGZO) thin‐film transistors. This work provides insights to the circuit behavior of display driver circuits at high frequencies and improving circuit reliability.

The development of Enhanced Geothermal Systems (EGS) for base-load electrical power generation will require electronics for sensing and control during exploration and drilling and also during production. The operating temperature environments for these applications will generally be more extreme than those encountered by electronics currently deployed for oil and gas development and production monitoring. To address this requirement, electronic components have been designed and fabricated for operation at temperatures of 300°C. These integrated circuits use silicon-on-insulator (SOI) fabrication processes to achieve high temperature operation. High-fidelity simulation models have been developed by characterization of SOI devices at 300°C. These device models were employed to design components required for the development of a down-hole orientation module. A wide-bandwidth, low-noise operational amplifier has been developed for use with MEMS accelerometer sensors. A multi-channel synchronous voltage-to-frequency converter with built-in reference and oscillators has also been developed for use with 3-axis flux-gate magnetometers. The components themselves are general purpose and could easily be used for other high-temperature sensor-interface applications. .

An overview of III-V MOSFET technological challenges in comparison to well-established heterostructure-based FET technologies is presented with an emphasis on required properties and possible solutions. Possible approaches to achieve thermodynamically stable high- k gate stack with low interface trap density are reviewed, followed with our results on amorphous Si interface passivation layer (IPL) in-situ deposited on top of GaAs or strained InGaAs MOSFET channels grown by molecular beam epitaxy. Main issues of Si IPL, namely increased equivalent oxide thickness due to IPL oxidation and Si diffusion into the semiconductor channel, are addressed using an in-situ deposited HfO 2 with ultrathin (down to 0.25 nm) Si IPL and controlling its bonding state at the interface. Enhancement mode inversion-type MOSFET with HfO 2 high- k oxide is demonstrated. The device employs amorphous Si interface passivation layer, sputter-deposited high- k oxide and metal TaN gate and modulation p-doped GaAs / AlGaAs heterostructure with inversion n -channel formed at the interface with the oxide. The MOSFET with equivalent oxide thickness of 3.7 nm and long 100 μm channel have maximum DC transonductance of 0.9 mS/mm, Ion/Ioff = 2×104 (at low Ioff of 30 nA) and effective channel mobility exceeding 1000 cm2/V-s at sheet electron density <2×1012 cm-2.

This paper describes the device technologies that will be instrumental in achieving 100-Gbit/s-class ultrahigh-speed lightwave communications systems and clarifies the device technology issues we must address before we can make such systems a reality. At the interface between optical and electrical units, their monolithic integration is necessary and a uni-traveling carrier photodiode (UTC-PD) enables us to simplify the interface circuits. In high-speed circuits, InP-based HEMT's and HBT's will still be key devices. Further scaling down of HEMT's and reduction of their parasitic capacitance are the major subjects to achieve 100 Gbit/s operations. For HBT's, reduction of the product of feedback capacitance and base resistance are necessary. Estimations of operation speed for basic circuits in lightwave communications systems are summarized to set targets for designing device structures.

Close monitoring of vital physiological parameters is often key in following the evolution of certain medical conditions (e.g., diabetes, infections, post-operative status or post-traumatic injury). The allocation of trained medical staff and specialized equipment is, therefore, necessary and often translates into a clinical and economic burden on modern healthcare systems. As a growing field, transient electronics may establish fully bioresorbable medical devices capable of remote real-time monitoring of therapeutically relevant parameters. These devices could alert remote medical personnel in case of any anomaly and fully disintegrate in the body without a trace. Unfortunately, the need for a multitude of biodegradable electronic components (power supplies, wires, circuitry) in addition to the electrochemical biosensing interface has halted the arrival of fully bioresorbable electronically active medical devices. In recent years molybdenum (Mo) and tungsten (W) have drawn increasing attention as promising candidates for the fabrication of both energy-powered active (e.g., transistors and integrated circuits) and passive (e.g., resistors and capacitors) biodegradable electronic components. In this review, we discuss the latest Mo and W-based dissolvable devices for potential biomedical applications and how these soluble metals could pave the way towards next-generation fully transient implantable electronic systems.

The article shows the possibility of convenient use of software simulators of electric circuits in performing laboratory works in physics, theory of electric circuits and signals, and the basics of electronics. An example of studying Kirchhoffʼs laws in the NI Multisim 14 simulator as one of the simplest in terms of interface but very powerful in terms of capabilities is considered. The choice of NI Multisim is due to the fact that it is de-facto one of the industrial standards in the real design of electronic devices. Thus, students are introduced to not an educational software simulator for modeling electrical phenomena, but to industrial software that they may have to deal with as future electronics designers.The article describes the structure of a typical mini-project (laboratory work) on the study of Kirchhoff's laws, and shows that this approach to organizing training is related to the specifics of teaching students majoring in 172 – “Telecommunications and Radio Engineering”, 123 – “Computer Engineering” and 125 – “Cybersecurity”.As a result, students acquire the skills to develop and test models of electrical circuits with visualization of the results obtained, learn to use the methods of solving systems of linear equations acquired in the course of mathematics in practice. Keywords: educational technologies of distance learning; simulation of electrical circuits; analysis of processes in electrical systems; use of NI Multisim 14 software package for educational purposes; laboratory works in physics and electronics; Ohm’s law; Kirchhoff's laws; virtual learning environment.

The results show that the obtained TiO2 films present a dielectric constant of approximately 40, a good interface quality with silicon and a leakage current density, of 70 mA/cm2 for VG = 1V, acceptable for high performance logic circuits and low power circuits fabrication, indicating that this material is a viable substitute for current dielectric layers in order to prevent tunneling currents.

As performant and well-established as conventional silicon-based electronics have become, the era of wearable electronics and the Internet-of-Things has created a demand for robust electronic devices that can conform to the surfaces of the human body. Whereas the mechanical mismatch between rigid silicon electronics and the human body represents a fundamental limit to conventional non-invasive health sensing, wearable electronics and electrodes that can conform to the microscopic features of the skin1,2 can circumvent most of the motion artifacts inherent to conventional, rigid sensing devices, and facilitate continuous health monitoring as is required for modern, more proactive healthcare. Unfortunately, without addressing this fundamental mechanical incompatibility, devices that leverage the high density of transistors available in rigid silicon-based integrated circuits are handicapped by how well they can maintain contact with the body, and consequently are prone to failure at the sensor-circuit interface. The extraordinary properties of two-dimensional materials pose a unique opportunity for addressing this mechanical mismatch. Their unusual mechanical strength combined with their ultimate thinness, optical transparency, and favorable electronic transport properties3 makes them ideal candidates for the next generation of highly conformable wearable electronics free of the constraints of a rigid silicon circuit board—however, minimizing local strain in the vicinity of the active devices to ensure reliable operation remains a priority. Using a design informed by finite element method (FEM) simulations, our proposed strain-neutralizing 2D transistors are configured to resist applied strains on the order of the 30% strains human skin can withstand by redistributing strain away from active regions. Tight binding simulations of the transistor channels helps with further compensation of residual strain in the active regions, alongside careful consideration of materials and device architecture during fabrication. Together, these considerations help realize the possibility of fully integrated strain-neutralized 2D transistors compatible with state-of-the-art conformable wearable sensors. [1]S.
