To meet low power requirements for Internet of Things (IoT) applications, the power dissipation of RF transceivers must be very low. As the Low Noise Amplifier (LNA) is one of the most energy consuming parts of an RF receiver, its power optimization is necessary for modern IoT devices. This work presents a 170 $\mu$W LNA capable of operating at 2.4 GHz when powered by a 0.4 V source. It is based on an inverter-based amplifier with improved gate bias voltage and automatic forward bulk biasing to operate at the moderated channel inversion level. A biasing metric is explored to analyze the best dimensions and bulk bias voltages for the NMOS transistor. Post-layout simulation results shown a 2.8 dB noise and competitive specification values compared to the state-of-the-art low-voltage LNAs.

Under the auspices of Defense Advanced Research Project Agency's Microsystems Technology Office (DARPA/MTO) Low Power Electronics Program, the Mayo Foundation Special Purpose Processor Development Group is exploring ways to reduce circuit power consumption, while maintaining or increasing functionality, for existing military systems. Applications presently being studied include all-digital radar receivers, electronic warfare receivers, and other types of digital signal processors. One of the integrated circuit technologies currently under investigation to support such military systems is the IBM Corporation silicon germanium (SiGe) BiCMOS process. In this paper, design methodology, simulations and test results from demonstration circuits developed for these applications and implemented in the IBM SiGe BiCMOS 5HP (50 GHz fT HBTs with 0.5 μm CMOS) and 7HP (120 GHz fT HBTs with 0.18 μm CMOS) technologies will be presented.

This work gives a design perspective on low-power and wideband RF-to-Baseband current-reuse receivers (CRR). The proposed CRR architecture design shares a single supply and biasing current among both LNTA and baseband circuits to reduce power consumption. The work discusses topology selection and a suitable design procedure of the low noise transconductance amplifier (LNTA), down-conversion passive-mixer, active-inductor (AI) and TIA circuits. Layout considerations are also discussed. The receiver was simulated in 130 nm CMOS technology and occupies an active area of 0.025 mm2. It achieves a wideband input matching of less than −10 dB from 0.8 GHz to 3.4 GHz. A conversion-gain of 39.5 dB, IIP3 of −28 dBm and a double-sideband (DSB) NF of 5.6 dB is simulated at a local-oscillator (LO) frequency of 2.4 GHz and an intermediate frequency (IF) of 10 MHz, while consuming 1.92 mA from a 1.2 V supply.

This paper presents a high linearity and low power Low-Noise Amplifier (LNA) for Ultra-Wideband (UWB) receivers based on CHRT 0.18[Formula: see text][Formula: see text]m Complementary Metal-Oxide-Semiconductor (CMOS) technology. In this work, the folded topology is adopted in order to reduce the supply voltage and power consumption. Moreover, a band-pass LC filter is embedded in the folded-cascode circuit to extend bandwidth. The transconductance nonlinearity has a great impact on the whole LNA linearity performance under a low supply voltage. A post-distortion (PD) technique employing an auxiliary transistor is applied in the transconductance stage to improve the linearity. The post-layout simulation results indicate that the proposed LNA achieves a maximum power gain of 12.8[Formula: see text]dB. The input and output reflection coefficients both are lower than [Formula: see text][Formula: see text]dB over 2.5–11.5[Formula: see text]GHz. The input third-order intercept point (IIP3) is 5.6[Formula: see text]dBm at 8[Formula: see text]GHz and the noise figure (NF) is lower than 4.0[Formula: see text]dB. The LNA consumes 5.4[Formula: see text]mW power under a 1[Formula: see text]V supply voltage.

High gain, wide bandwidth, low noise, and low-power transimpedance amplifiers based on new BiCMOS common- base topologies have been designed for fiber-optic receivers. In particular a design approach, hereafter called "A more- FET approach", added a new dimension to effectively optimize performance tradeoffs inherent in such circuits. Using conventional silicon 0.8 μm process parameters, simulated performance features of a total-FET transimpedance amplifier operating at 7.2 GHz, which is close to the technology fT of 12 GHz, are presented. The results are superior to those of similar recent designs and comparable to IC designs using GaAs technology. A detailed analysis of the design architecture, including a discussion on the effects of moving toward more FET-based designs is presented.

This paper has been carried out the study of reconfigurable wide-band mixers that can do the frequency conversion and gain variation standards with low noise and high linearity used in multi-mode and multi-standard receivers. Over the last few years reconfigurability has become very popular in adopting technology to meet the wideband wireless communication specifications that is compatible with multi-standards like GPS (1.57 GHz), WLAN (2.4 GHz - 5.9 GHz), Bluetooth (2.402 – 2.483 GHz) and ZigBee (0.784 - 0.915 GHz) in low power consumption environment. The reconfigurability can be achieved between low and high band modes through power switching in RF frequency mixers. It can be achieved by flipping the input RF signal between gate and source terminal of input transistor and altering the trans-impedance stage output. With the concept of reconfigurable transistor pair with open and short circuit stubs, one can not only find the configurable gain with center frequencies 7.355, 8.65, 11.35 and 12.65 GHz but also with high power efficiency. Tow Thomas Bi-Quad Topology other than the traditional current commuting technique for the second order trans-impedance amplifier stage, works as a current mode filter over a tunable bandwidth. The active Gilbert mixers are used widely in most of communication system, due to its significance gain, perfect isolation, and linearity in response.

In this thesis, the radios which are suitable for Wireless Personal Area Network (WPAN) applications are designed and implemented. The thesis consists of two parts. The first part focuses on studying various low-power techniques and realizes two different 2.4-GHz low-power receivers. The second part implements high quality component circuits which are suitable for 60-GHz band applications. First, we study different low-power techniques. Because the passive mixer is a common component of a direct-conversion receiver, we also investigate the flicker noise of passive mixers. Then, we implement a 2.4-GHz low-power receiver with passive mixers, and a 2.4-GHz low-power receiver with subthreshold biasing technique. Both chips are implemented in TSMC 0.18-um CMOS technology. Second, we implement different types of 60-GHz sub-harmonic upconverters in TSMC 0.13-um CMOS technology, and propose transformer-type balun to combine RF signal. In order to provide good LO source, we design a QVCO using three-line coupler. This QVCO operates at 0.6V, and consumes 7.6mW. And the FoM is -203.6dBc/Hz.

Two low-IF receiver RFICs and two T/R switches for 2.4 GHz wireless personal network applications have been designed in this thesis work. The first receiver front-end CMOS RFIC includes a low-noise amplifier and a down-mixer. The measured results showed power gain of 11.2 dB, input P1dB of —19.5 dBm, input IP3 of —15 dBm, noise figure of 8.2 dB, and LO-RF isolation greater than 47 dB, where the total DC power consumption is below 9.1 mW. The second single-chip receiver IC includes a low-noise amplifier, a down-mixer, an IF variable gain amplifier, a high-order low-pass filter and a buffer amplifier, which was implemented with TSMC 0.18um CMOS technology. The peak-voltage of baseband input I/Q signals was greater than 600 mV, which was sufficient to drive the following A/D converter. The simulated 66 dB gain tuning range was, adequate to cover the dynamic range of WPAN received RF signal. The entire chip consumed less than 12.7 mW DC power. For the T/R switches, SPDT and DPDT switches were designed with feedback inductions such that the measured isolation was larger than 31.5 dB and insertion loss was less than 1.4 dB.

With recent advances in the high-frequency characteristics, CMOS has become very attractive process for the implementation of low-cost wireless communication systems. In addition to conventional RF systems, low-power and low-voltage applications, such as RFID and wireless sensor networks, have motivated the development of fully integrated transceivers using CMOS process. However, the inherently low transconductance and the required threshold voltage for CMOS process make it extremely difficult to operate reduced supply voltage and power dissipation. In this thesis, a down-conversion mixer, a voltage-controlled oscillator (VCO) and a receiver frontend fabricated in 0.18-μm CMOS are presented to demonstrate the potential of CMOS frontend circuits for low-power and low-voltage operation. A novel mixer with stacked complementary transistors and a current bleeding resistor is proposed for low-voltage application while maintaining reasonable conversion gain. The 5.2-GHz mixer exhibits a conversion gain of 3dB and an IIP3 of -8dBm with a power dissipation of 792 μW from a 0.6-V supply voltage. As for the proposed VCO topology, the tail current source of a LC-tank VCO has been eliminated to support ultra-low voltage operation. 5.8-GHz VCO achieves a tuning range of 8.9% and phase noise of -97dBc/Hz @ 1MHz. The VCO core consumes 696-μW dc power from a 0.6-V supply voltage. Finally, by combining the fabricated mixer, VCO with a single stage LNA, the receiver frontend is designed for the 5-GHz frequency band. Based on the simulation results, the receiver frontend demonstrates a conversion gain of 15dB and IIP3 of -19dBm. The complete receiver is operated at a reduced supply voltage of 0.6 V with a power dissipation of 2.3mW.

This thesis aims at design of a low-voltage low-power receiver front-end circuit applicable to wireless sensor networks. Two chips are realized. In the first chip, a low-power double-balanced mixer is designed in a folded topology. A transconductance stage with phase splitting function which is composed of a common-gate and common-source transistors is adopted for low power consideration. Output balanced condition, input matching, and noise of the transconductance stage are analyzed. Realized in 0.18-um CMOS technology, the measured input return loss and voltage conversion gain are 11dB and 10.4dB, respectively. The input third-order intercept point (IIP3) is 3.8dBm while consuming 2mW from a 1V supply. In the second chip, a receiver front-end circuit is designed for low supply voltage as low as 0.6V. The circuit consists of a low noise amplifier, switching stage, and on-chip transformer which provides AC coupling between stages connected to it in a folded structure. The transformer is designed not only to convert single-ended signal into differential form without excess power consumption, but also to operate in resonant mode to have current transfer gain. The power consumption of the circuit is effectively cut down. Also, a figure of merit for bias consideration and stabilization design for LNA is analyzed for the optimum design condition under low supply voltage case. The measured input return loss and voltage conversion gain are 16.9dB and 12dB, respectively. The input third-order intercept point (IIP3) is -2.8dBm while consuming only 0.29mW from a 0.6V supply.

This thesis consists of two parts. All the proposed circuits were implemented in TSMC 0.18μm mixed-signal/RF CMOS 1P6M technology.   Part I presents an ultra-wide band low-noise amplifier applied to WPAN (Wireless Personal Area Network.), and a common gate architecture and noise-cancelling technique are employed in this amplifier. Using these techniques can not only suppress the total noise contribution in the output but increase the total gain with an excellent input wideband matching. According to the measured results, the LNA achieves the small signal gain of 9.7~11.6 dB, a noise figure of 4.54~4.85 dB, the input P1dB of -19 dBm, and the input IP3 of -9.5 dBm over the whole working range. The power consumption is about 16.9 mW at the supply voltage of 1.8V.   Part II proposes a low-power high-gain receiver front-end applied to 24-GHz ISM band. The receiver front-end contains a low-noise amplifier, a transformer balun, a down-conversion mixer and an intermediate frequency amplifier. In LNA design, using two stage common source structure cascaded with common gate structure realizes performance of high gain and low-noise with the limited power dissipation; in down-conversion mixer design, making use of cross-coupling and current-bleeding techniques obtains high gain and low power consumption. Furthermore, an intermediate frequency amplifier is added after the down-conversion mixer so the whole conversion gain increases once more. Therefore, the proposed receiver front-end has advantage of low power and high gain compared to other researches. This circuit achieves a conversion gain of 37.1 dB and a double-side band noise figure of 5.65 dB with the input P1dB of -33.5 dBm, output P1dB of 2.1 dBm, and input IP3 of -23 dBm consuming 37.1 mW.

This work describes the design of a wireless receiver front-end circuit for Bio-Acquisition in Wireless Sensor Network (WSN). The front-end circuit includes a cascode low noise amplifier (LNA), an active balun and a folded-cascode even-harmonic mixer. The balun employs differential amplifier architecture utilizing the concept of RC feedback to transform single-ended signal into differential form. The frequency-doubling circuit in the LO stage is employed to double the LO frequency, thus the self-mixing resulted from LO leakage could be avoided. The even-harmonic (EH) mixer with folded technique and complementary frequency-doubling circuits is adopted for low voltage topology to achieve large stable LO turning range. This work possesses conversion gain of 8.5 dB, 1-dB compression point (IP1dB) of -36 dBm, power consumption of 5.0 mW at 1V supply voltage.

Ultra-wideband (UWB) is an alternative wireless communications technology that offers high bandwidth wireless communications without the constraints of spectrum allocation. Fundamentally different from conventional radio frequency communications, UWB relies on a series of narrow, precisely timed pulses to transmit digital data. Transmitters and receivers that use UWB can be much simpler to build than their conventional counterparts, resulting in lower cost and higher power efficiency. Moreover, the inherent properties of UWB emissions allow them to potentially coexist with conventional wireless systems on a noninterfering basis. In April 2002, the Federal Communications Commission (FCC) released UWB emission masks and introduced the concept of coexistence with traditional and protected radio services in the frequency spectrum, which allows the operation of UWB systems mainly in the 3.1 to 10.6 GHz band, limiting the power level emission to -41dBm/MHz. Within the power limit allowed under the current FCC regulations, Ultra-wideband can not only carry huge amounts of data over a shortto- medium distance at very low power (this range can be extended by using ad-hoc or mesh networks), but it also has the ability to carry signals through doors and other obstacles that tend to reflect signals at more limited bandwidths and a higher power (Reed, 2005). At higher power levels, UWB signals can travel to significantly greater ranges. In March 2005, the FCC granted the waiver request, filed by the multiband Orthogonal Frequency Division Multiplexing (OFDM) alliance (MBOA), in which it approved the change in measurement for the all UWB technologies (neutral approach) (Barret, 2005). The FCC’s waiver grants effectively removes the previous transmit power penalties for both frequency-hopping (OFDM) and gated UWB technologies (TH and DS). Hence, they are allowed to transmit at higher power levels and then become idle for some time, as long as they meet the limits for average power density. This new rules allow those technologies to achieve up to four times better performance and double the range.

In the extremely high frequency radio spectrum of 30-300 GHz, the band from 57-64 GHz has been de-regulated. The biggest challenge in designing products at this frequency is the design of CMOS based transceiver circuit components. This chapter deals with the review of 60 GHz LNA design. LNA was chosen as this is the first component of the receiver circuit and its performance affects the transceiver efficiency. In this chapter the review is done on 60GHz LNA's design addressing the linearization, and low power challenges. To address these challenges, in literature there are many LNA architectures such as simple cascode topology, Current reuse topology etc. The major advantage of current reuse topology is its load transistor shares the same bias current of driver which results in reduced power dissipation by maintaining the maximum gain. The main objective of this chapter is to address gain, power dissipation and linearization challenges by reviewing the different current reuse architectures and linearization techniques used to implement 60GHz LNA.

The switch is developed using a commercial 0.15 µm GaAs pHEMT technology. It achieves low loss and high isolation for millimeter wave applications. The circuit and layout drawing of SPDT switch are done by using Advanced Design System (ADS) software. The layout is verified by running the Design Rules Check (DRC) to check and clear all the errors. At the operating frequency of 30 GHz, the reported SPDT switch has 1.470 dB insertion loss and 37.455 dB of isolation. It also demonstrates 26.00 dBm of input P1dB gain compression point (P1dB) and 22.975 dBm of output P1dB. At a supply voltage of 3.0 V and 30 GHz operating frequency, this two-stage LNA achieves an associated gain of 21.628 dB, noise figure (NF) of 2.509 dB and output referred 1-dB compression point (P1dB) of -11.0 dBm, the total power consumptions for the LNA is 174 mW. At a supply voltage of 6.0 V and 30 GHz operating frequency, a 2-stage MPA achieves a linear gain (S21) of 13.236 dB, P1dB of 22.5 dBm, power gain of 11.055 dB and the PAE of 14.606%. The total power consumption for the MPA is 1.122 W. The 30 GHz LNA and PA can be applied in direct broadcast satellite (DBS), automotive radar transmitter and receiver.

This chapter deals with the concept of first time right IC. A development of subsystems for wireless application is used as test case. The subsystems are Low Noise Amplifier (LNA), Medium Power Amplifier (MPA) and Variable Signal Generator (VSG). Several issues such as suitable multiband design flow and high speed switch must be solved. A new design methodology of integrated circuits for multiband application is presented. The design methodology is modified from a typical Monolithic Microwave Integrated Circuit (MMIC) flow. Core based design, parasitic aware approach and power constrained optimization are introduced into the new design flow. The same core circuit topology is used as main block to design 2.4 GHz and 3.5 GHz LNA and MPA. A power constrained optimization is applied to a test case amplifier i.e. broadband amplifier to get the optimized RF performance. The optimization is simulation-based technique. A 0.15 µm 85 GHz PHEMT is used in designing the LNA, MPA and broadband amplifier. This chapter also introduces the inventions of Voltage Controlled Oscillator (VCO), Mixer, Low Noise Amplifiers (LNA), Power Amplifiers (PA) and Transmit-Receive Switch (T/R). These circuits are crucial components for RF and Microwave front-end integrated circuits. The elements of inventions of circuits are clearly explained. The inventions reflect the requirement or the need of solving current problem using available technology.

For the past years, the Internet of Things (IoT) supported by 5G technology, has been expanding rapidly across a wide range of services, enabling inter-object connectivity for the automotive industry, consumer electronics, transportation, logistics sectors, and manufacturing. With the increasing ubiquitous usage of various small-sized sensors, manufacturing cost of each element taken remains a critical aspect. Relatively low price of individual elements is the key for enabling tightly connected environment, but may severely affect RF chains quality as well as overall performance. With 5G expansion to the sub-THz bands, power amplifier nonlinearity may significantly limit system performance even in high- grade devices, due to power amplifier design limitations. Multiple studies were done to mitigate nonlinearity impact, both at the transmitter (TX) and receiver (RX) sides. Many solutions propose for evaluation and further compensation of the PA nonlinearity effects, via decision-directed feedback, training or even statistical processing of the received signal. However, with knowledge of the PA nonlinearity function at the receiver side, the processing may be simplified by the application of the reverse function to the equivalent signal in the time domain. In this paper we propose a method for PA nonlinear distortion compensation at the RX side, which can be adjusted for several signal waveforms adopted in 5G NR (New Radio) standard, such as CP-OFDM, DFT-S-OFDM, and others. The simulation results presented demonstrate performance improvement both for the sub-THz PA models and models for the 30–70 GHz band.

This chapter describes some basic characteristic responses that must be known for each Monolithic Microwave Integrated Circuits. The main parameters such Return Loss, Insertion Losses or Gain, Power at 1dB compression, InterModulation Products or Noise Figure are very important and have to be measured before using the device in final applications. Basic rules of Test and Measurement in RF and Microwaves, as well for characterization on benches as for high volume production using Automatic Test Equipments installed in test platforms, are summarized for helping today’s test engineers to develop their own test solutions. The device, that was characterized on bench and tested in production environment, is a monolithic, integrated low noise amplifier (LNA) and mixer usable in RF receiver Front-End applications for Personal Communications functioning on frequency wideband between 0.1 and 2.0 GHz.
