Digital oscilloscope’s structure has analog signal acquisition circuit, which transforms signal’s amplitude to fit ADC dynamic range. This circuit is commonly called oscilloscope’s vertical or front-end amplifier. Difficulty in designing front-end amplifiers in GHz range largely affects higher frequency range oscilloscope’s price. This work is focused on designing a front-end amplifier using discrete and openly sold components. We propose a design for attenuator, buffer, variable gain circuits. Amplifier’s prototype is designed. Main characteristics of the amplifier were measured. Measured bandwidth is 3 GHz. Amplifier’s gain and attenuation can support vertical scale sensitivity range from 10 mV/div to 1 V/div. Step response distortion is under 10 %. SMD and PTH relay model attenuators were evaluated. In this paper we review oscilloscope’s front-end purpose and structure. We review amplifiers design and provide the results of experimental measurements.

In the development of power amplifiers, MOSFETs are widely used in the composition of the manufacture. As is known, MOSFETs have a longer on-off time loss compared to IGBT. The loss on the on-off time has an impact on the heat generated by the MOSFET. Class D Audio Amplifier is basically a Switching-Amplifier or Pulse Width Modulation-Amplifier. High efficiency means that it will produce low power dissipation, thus the power wasted is relatively lower when compared to class A, B or AB amplifiers. Because the class D audio amplifier can be said to be more economical because it does not require a large heatsink and a large power supply. The manufacture of the Class D power amplifier system uses a voltage of 28.5 volts DC on the final transistor IRF9530 AND IRF630 measuring the input transistors of 3.3 volts DC, 28.5 volts DC. In the test using an oscilloscope type LS 8050, 50 MHz frequency, the position of the audio input off of the amplifier has sound defects. Testing of the power amplifier is carried out when the treble on the input tone control is full db in the defective amplifier wave.

Abstract Since the so-called Hopf-type amplifier has become an established element in the modeling of the mammalian hearing organ, it also gets attention in the design of nonlinear amplifiers for technical applications. Due to its pure sinusoidal response to a sinusoidal input signal, the amplifier based on the normal form of the Andronov-Hopf bifurcation is a peculiar exception of nonlinear amplifiers. This feature allows an exact mathematical formulation of the input-output characteristic and thus deeper insights of the nonlinear behavior. Aside from the Hopf-type amplifier we investigate an extension of the Hopf system with focus on ambiguities, especially the separation of solution sets, and double hysteresis behavior in the input-output characteristic. Our results are validated by a DSP implementation.

RF power amplifiers are one of challenging blocks in designing radio frequency transceivers, this is due to non-linearity behavior of power amplifiers that leads to inter-modulation distortion. This paper presents the design of wide-band power amplifier which combined with parallel coupled line band pass filter at the input and output of power amplifier to allow the only required frequency band to pass through the power amplifier. Class-A topology and ATF-511P8 transistor are used in this design. Advanced Design System software used as a simulation tool to simulate the designed wide-band power amplifier. The simulation results showed an input return loss (S11) which less than -10dB, and gain (S21) is higher than 10 dB over the entire frequency band and considers as flat as well. The designed amplifier is stable over the bandwidth (K>1). Inter-modulation distortion is -56.919dBc which is less than -50dBc with 10dBm input power. The designed amplifier can be used for the microwave applications which include weather radar, satellite communication, wireless networking, mobile, and TV.

This paper proposes a low noise readout integrated circuit (IC) with a chopper-stabilized multipath operational amplifier suitable for a Wheatstone bridge sensor. The input voltage of the readout IC changes due to a change in input resistance, and is efficiently amplified using a three-operational amplifier instrumentation amplifier (IA) structure with high input impedance and adjustable gain. Furthermore, a chopper-stabilized multipath structure is applied to the operational amplifier, and a ripple reduction loop (RRL) in the low frequency path (LFP) is employed to attenuate the ripple generated by the chopper stabilization technique. A 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) is employed to convert the output voltage of the three-operational amplifier IA into digital code. The Wheatstone bridge readout IC is manufactured using a standard 0.18 µm complementary metal-oxide-semiconductor (CMOS) technology, drawing 833 µA current from a 1.8 V supply. The input range and the input referred noise are ±20 mV and 24.88 nV/√Hz, respectively.

AbstractWe will theoretically and experimentally study the effect of the linewidth and the frequency of a weak detuned signal on its amplified spectrum in the Brillouin amplifier. We will show that the spectral profile of the input signal is preserved during amplification only when the signal linewidth is much narrower than the Brillouin linewidth of the amplifier. If the signal linewidth is near or above the Brillouin linewidth, the frequency shift of the amplified signal with respect to the pump will be close to the Brillouin shift of the amplifier, and will be independent of the frequency shift of the input signal.

<span>In this paper, a Doherty power amplifier was designed and simulated at 2.4 GHz central frequency which has high efficiency. A Doherty power amplifier is a way to increase the efficiency in the power amplifiers. OMMIC ED02AH technology and PHEMT transistors, which is made of gallium arsenide, have been used in this simulation. The Doherty power amplifier unique feature is its simple structure which is consisting of two parallel power amplifiers and transmission lines. In order to integrate the circuit, the Doherty power transmission amplifier lines were implemented using an inductor and capacitive components. Also, the Wilkinson power divider is used on the chip input. To improve the efficiency, the auxiliary amplifier dimensions is selected enlarge and the further input power is allocated it by the power divider. A parallel R-C circuit has been used at the input of transistors to improve their stability. Simulation results show that the Doherty power amplifier has 17.2 dB output power gain, 23 dBm maximum output power, and its output power P<sub>1dB</sub> =22.6dBm at compression point -1 dB, also, its maximum efficiency is 55.5%.</span>

A study of the front-end electronics for quartz tuning forks (QTFs) employed as optoacoustic transducers in quartz-enhanced photoacoustic spectroscopy (QEPAS) sensing is reported. Voltage amplifier-based electronics is proposed as an alternative to the transimpedance amplifier commonly employed in QEPAS experiments. The possibility to use differential input/output configurations with respect to a single-ended configuration has also been investigated. Four different architectures have been realized and tested: a single-ended transimpedance amplifier, a differential output transimpedance amplifier, a differential input voltage amplifier and a fully differential voltage amplifier. All of these amplifiers were implemented in a QEPAS sensor operating in the mid-IR spectral range. Water vapor in ambient air has been selected as the target gas species for the amplifiers testing and validation. The signal-to-noise ratio (SNR) measured for the different configurations has been used to compare the performances of the proposed architectures. We demonstrated that the fully differential voltage amplifier allows for a nearly doubled SNR with respect to the typically used single-ended transimpedance amplifier.

This paper analyzes the noise properties of balanced amplifier configurations in terms of noise waves and discusses the effect of various amplifier configurations on the noise and signal parameters. It shows how the noise generated in the load on the input coupler of a balanced amplifier deteriorates the amplifiers noise resistance parameter with respect to that of its component amplifiers. The properties of two new balanced amplifier configurations will be discussed, which enable the reduction or elimination of this deterioration.

The power amplifier circuit is a circuit used to amplify or magnify input signals. The use of a transistor as an amplifier is that the current on the base is used to control the larger current given to the collector through the transistor. The small current change on the controlling base is what is called a large change in the current flowing from the collector to the emitter. The advantages of the amplifier transistors can not only amplify the signal, but these transistors can also be used as current amplifiers, voltage amplifiers and power amplifiers.

Body-channel communication (BCC) is based on the principle of electrical field data transmission attributable to capacitive coupling through the human body. It is gaining importance now a day in the scenario of human centric communication because it truly offers a natural means of interaction with the human body. Traditionally, near field communication (NFC) considers as a magnetic field coupling based on radio frequency identification (RFID) technology. The RFID technology also limits the definition of NFC and thus reduces the scope of a wide range of applications. In recent years BCC, after its first origin in 1995, regain importance with its valuable application in biomedical systems. Primarily, KAIST and Philips research groups demonstrate BCC in the context of biomedical remote patient health monitoring system. BCC transceiver mainly consists of two parts: one is digital baseband and the other is an analog front end (AFE). In this thesis, an analog front end receiver has presented to support the overall BCC. The receiver (Rx) architecture consists of cascaded preamplifier and Schmitt trigger. When the signals are coming from the human body, they are attenuated around 60 dB and gives weak signals in the range of mV. A high gain preamplifier stage needs to amplify these weak signals and make them as strong signals. The preamplifier single stage needs to cascade for the gain requirement. The single stage preamplifier, which is designed with ST65 nm technology, has an open loop gain of 24.01 dB and close loop gain of 19.43 dB. A flipped voltage follower (FVF) topology is used for designing this preamplifier to support the low supply voltage of 1 V because the topology supports low voltage, low noise and also low power consumption. The input-referred noise is 8.69 nV/sqrt(Hz) and the SNR at the input are 73.26 dB. The Schmitt trigger (comparator with hysteresis) is a bistable positive feedback circuit. It builds around two stage OTA with lead frequency compensation. The DC gain for this OTA is 26.94 dB with 1 V supply voltage. The corner analyzes and eye diagram as a performance matrix for the overall receiver are also included in this thesis work.

Operational amplifiers continue to develop to meet modern demands on performance. This document describes an operational amplifier designed for a highly specific telecommunications application - to serve as the buffer between an I/Q demodulator and Gm-C filter. Requirements set forth by this application call for a wide common mode input range, stretching from ground to the positive supply, and a programmable output offset, offering up to ±25mV differentially from the output common mode. This programmable offset is implemented using two complementary current mode digital-to-analog converters (DACs) directly driving the input pins of the operational amplifier. The output offset is serially programmed with a three pin SPI interface. In addition to programming the offset DACs, the SPI interface is also designed to be able to program four additional parameters necessary for the function of the programmable Gm-C filter, into which the opamp will be integrated.

Abstract The goal of this dissertation was to study and model the settling transient response of switched-capacitor (SC) circuit, which is the most important building block of Analog-to-Digital converters (ADCs), and to improve the settling performance of the SC circuit implemented in ADC in CMOS technology. In the design of the SC circuit, there are common obstacles in obtaining a precise and fast settling with low power consumption. The main contribution of this thesis is to speed up different SC circuits without adding extra power consumption or to achieve the required settling precision with low power consumption. Two solutions to reduce the power consumption of SC integrators in sigma-delta (SD) ADCs were designed and verified by simulations. These implementations are based on the passive charge redistribution technique by injecting a precalculated open-loop charge in the output of the first integrator. The injected charge was implemented either by a continuous function of the input and feedback voltages or by quantizing to three levels. In both cases, the idea is to minimize the initial transient voltage in the input of the first OTA and hence bypass the slewing of the OTA. Another approach was proposed for the traditional SC residue circuit of the pipeline ADC, where a load capacitor is connected to the output during the evaluation phase. Here, a pre-charge of the load capacitance can be used. One proposed implementation is called the continuously controlled pre-charged technique. It pre-charges the load capacitor to the proper voltage during the previous phase, connects the pre-charged load capacitor to the output of the OTA during the evaluation phase, and hence pulls the charge sharing so that the initial input step of the OTA is instantaneously minimized. The other implementation called the minimal pre-charged method implemented for the SC residue circuit of the pipeline ADC is to simply pre-charge the load capacitor with the fixed existing voltage, minimized the spread of the initial input voltage. This proposed technique did not require any additional active components
Tiivistelmä Kytkettyihin kapasitansseihin (SC-tekniikka) perustuvat vahvistimet ovat CMOS-tekniikkaan perustuvien analogia-digitaalimuuntimien (AD-muunnin) tärkeimpiä osia. Tämän väitöstyön tavoitteena oli tutkia ja mallittaa SC-tekniikkaan perustuvien vahvistinpiirien asettumisaikaa, ja etsiä piiriteknisiä keinoja asettumisajan nopeuttamiseksi. SC-piirien suunnittelun suurimpia ongelmia on saavuttaa tarkka ja nopea asettuminen mahdollisimman pienellä tehonkulutuksella. Tämän työn päätuloksina on joukko keinoja, joilla voidaan nopeuttaa SC-kytkettyjen vahvistimien asettumista ilman että niiden tehonkulutusta lisätään, tai saavuttaa aiempi suorituskyky pienemmällä tehonkulutuksella. Menetelmät perustuvat siihen, että SC-piirin passiivista varausjakautumista ohjataan niin, että vahvistimen tulosolmussa oleva transientti minimoituu, jolloin vahvistin ei ajaudu virtarajoitteiselle toiminta-alueelle, vaan sen asettuminen nopeutuu merkittävästi. Sigma-delta-tyyppiset AD-muuntimet koostuvat SC-integraattoreista, ja näiden asettumisen nopeuttamiseen kehitettiin ja varmennettiin simuloiden kaksi tapaa. Varauksen jakautumista autettiin syöttämällä erillisellä varauspumpulla transkonduktanssivahvistimen lähtösolmuun tietty, integraattorin tilasta ja tuloista riippuva varaus. Tällöin vahvistimen tulossa näkyvä alkutransientti pienenee, ja vahvistin ei ajaudu virtarajoitteiselle toiminta-alueelleen, jolloin sen asettumisvirhe pienenee merkittävästi. Varausinjektio toteutettiin kahdella eri tavalla: laskemalla tarvittava varaus joko jatkuvana funktiona tulosignaaleista, tai approksimoimalla sitä muutamalla diskreetillä tasolla. Pipeline-tyyppisissä AD-muuntimissa peruslohko koostuu SC-kytketystä vahvistimesta, jonka kuormakapasitanssi on kytkettynä vahvistimen lähtöön asettumisen aikana. Tämän kapasitanssin esivaraaminen sopivasti tarjoaa hyvin yksinkertaisen keinon ohjata varausjakautumista niin, että vahvistimen tulossa oleva transientti saadaan minimoitua ja toiminta virtarajoitteisessa moodissa vältettyä. Tässäkin tapauksessa kehitettiin ja varmennettiin kaksi vaihtoehtoista toteutusta. Ensimmäisessä kuormakapasitanssin esivarausjännite lasketaan tulosuureiden jatkuvana funktiona erillisellä summausvahvistimella. Toisessa, hyvin minimalistisessa ratkaisussa esivaraukseen käytetään kolmea käytettävissä olevaa kiinteää jännitettä. Tämä menetelmä ei vaadi lainkaan ylimääräisiä aktiivikomponentteja

The aim of this diploma thesis is to design active frequency filters based on passive RLC prototype. Three methods of the design of active filters and active functional blocks of electronic circuits working in current or mixed mode are used to this purpose. These blocks allow to process electrical signals with frequencies up to low tens of megahertz. In addition they feature for instance with high slew rate and low supply voltage power. Active high-pass and low-pass 2nd order filters are designed using simulation of inductor by active subcircuit method. Grounded and subsequently floating synthetic inductor is made with the current conveyors in the first case and with the current operational amplifiers with single input and differential output in the second case. This method advantage is relatively simple design and disadvantage is great quantity of active functional blocks. Active filters based on passive frequency ladder 3rd order filter while only one floating inductor is connected, are designed with circuit equation method. In the first design differential input / output current followers are used and in the second case current-differencing buffered amplifiers are used. This method benefits by smaller active blocks number and disadvantage is more complex design of the active filter. Active filter based on passive prototype of low-pass 3rd order filter with two floating inductors is designed with Bruton transformation method. Final active filter uses current operational amplifiers with single input and differential output which together with other passive elements replace frequency depending negative resistor, which arise after previous Bruton transform. This method usage is advantageous if the design consists of larger quantity of inductors and less number of capacitors. High-pass 2nd order filter is simulated by tolerance and parametrical analyses. Physical realisation utilising current feedback operational amplifier which substitute commercially hardly accessible current conveyors is subsequently made. Measurements of constructed active filter show that additional modifications, which allow better amplitude frequency characteristics conformity, are necessary.

The purpose of this work was to make a proposal for input parts of receiver for band 430 to 440 MHz. A model of chosen semiconductor triode BFP540 was created in simulation software. Possibilities how to decrease consumption of this semiconductor triode, keeping the profit, were investigated through the simulation.In compromise consumption, keeping the profit of the amplifier - an optimal operating point for this semiconductor triode UCE = 1,2 V and IC = 2 mA was found. It was tested through the testing wiring with noise microstrips conformity. Ascertained knowledge was used for construction of tuner for UHF receiver. An operating point of input amplifier of UHF receiver was owing to power supply amplifier forced for bigger effectiveness to UCE = 2,65 V and IC = 2,0 mA. Suppression of mirror frequency is provided with Helix filter of the third order, because of intermediate frequency 10,7 MHz. Mixing on intermediate frequency is made again by semiconductor triode BFP540. Selectivity of receiver is provided with intermediate frequency crystal filter 10,7 MHz with bandwidth 15 kHz. Designed input part enables reception of SSB, FM and digital types of modulation.Bandwidth intermediate frequency exit is adapted to this request To receive particular modulation , it is necessary to complete intermediate frequency signal way with appropriate intermediate frequency filter.

Acute pain as a result of tissue damage is self-limiting. Impulses are generated in primary sensory nerves by chemical mediators released from the damaged tissues. The spinal cord receives these impulses in the dorsal horn. At the level of the spinal cord, the impulses can be amplified or reduced in amplitude by descending inputs. At the level of the spinal cord, the representation of the painful area and the sensitivity of other, surrounding areas can be modified. At the level of the brainstem and thalamus, further modification can take place. The final perception of the pain can be modified by other central phenomena such as anxiety and fear. New imaging techniques have allowed a greater understanding of cortical representation of pain. The role of the glia in maintaining painful states is evolving.

The bipolar operational amplifier is an important kind of electronic device used in the nuclear reactor control system and its radiation damage threatens the reliability of nuclear operation. In order to explore the degradation of the bipolar operational amplifier induced by reactor neutron and gamma irradiation, radiation experiments were accomplished on particular bipolar operational amplifiers OP07 manufactured by Texas Instruments and Analog Devices. The amplifiers were irradiated in three different environments respectively: individual neutrons, individual gamma rays and mixed irradiation of reactor neutrons and gamma rays simultaneously. The results indicate that for both types of bipolar operational amplifiers, the degradations of the input bias current and the input offset voltage induced by the mixed irradiation of reactor neutrons and gamma rays simultaneously are notably more severe than the simple sum of neutron and gamma degradations measured individually. The mixed irradiation of reactor neutron and gamma rays simultaneously leads to degradation enhancement compared to individual ones and induce ionizing/displacement synergistic effects in the amplifiers. Enough attention should be paid to the degradation enhancement induced by the mixed irradiation for devices may exhibit unexpected failure during reactor operation and accelerate the aging of the nuclear reactor control system.
