DESIGN AND IMPLEMENTATION OF A FOUR TERMINAL FLOATING AMPLIFIER AND ITS APPLICATION IN ANALOG ELECTRONICS By José A. García Rivera The field of analog electronics has developed and matured for the past two decades. Within this field, design of analog amplifiers has received attention due to changes in technology. Amplifier circuits, considered analog devices, are found anywhere in many house el...

A novel technique for a self-equalized distributed amplifier is presented by showing the analogy between transversal filters and distributed amplifier topologies. The appropriate delay and gain coefficients of amplifier circuit are obtained by a Fourier expansion of the raised cosine spectrum in the frequency range of 0-40GHz.

A High Swing Ultra-Low-Power Two Stage CMOS OP-AMP in 180 nm and 350nm Technology with 1.5V supply, is presented. Cascode technique has been used to increase the dc gain. The unity-gain bandwidth is also enhanced using a gain-stage in the Miller capacitor feedback path. It have 92.45 degree phase margin. The circuit has 94.866dB gain for 180nm. The power dissipation of the designed only is appr...

The static characterization of the output section of the Arbitrary Waveform Generator (AWG) requires that its output signal must be digitalized by Analog to Digital Converter (ADC) with higher linearity and resolution than the device under test. In the literature, the problem of high resolution acquisition is translated to the simpler problem of low resolution and high sampling frequency acquis...

In this paper a new method for the design of a linear phase distributed amplifier in 180nm CMOS technology is presented. The method is based on analogy between transversal filters and distributed amplifiers topologies. In the proposed method the linearity of the phase at frequency range of 0-50 GHz is obtained by using proper weighting factors for each gain stage in cascaded amplifier topology....

We demonstrate how it is possible to increase the sensitivity of current noise measurement systems by exploiting the properties of a differential transconductance amplifier coupled with a four channels measurement system. In particular, it is demonstrated that, in proper conditions and by a proper elaboration of the acquired signals, the noise contribution coming from the active and passive dev...

The proposed buffer achieves high-speed driving performance while drawing a low quiescent current during static operation. The circuit offers enhanced slewing capabilities with limited power consumption by exploiting a slew detector which monitors the output voltage of the inp...

The paper presents a new voltage-mode universal filter using a differential voltage current conveyor transconductance amplifier (DVCCTA). It has three inputs and single output. The proposed circuit can simultaneously realize low-pass, band-pass, and high pass, band reject and all pass filter functions without changing the circuit topology and passive elements. The circuit exhibits a good freque...

This paper presents a Sub-mW differential Common-Gate Low Noise Amplifier (CGLNA) for ZigBee standard. The circuit takes the advantage of shunt feedback and Dual Capacitive Cross Coupling (DCCC) to reduce power consumption and the bandwidth extension capacitors to support 2.4 GHz ISM band. An amplifier employing these techniques has been designed and simulated in 0.18 mm TSMC CMOS technology. T...

The Operational Transconductance Amplifier is a basic building blocks found in many analog circuits such as data converter’s (ADC& DAC) and Gm-c filters. The OTA is an amplifier whose differential input voltage produces an output current .Thus ,it is a voltage controlled current source(VCCS) whereas the Op-amp are voltage controlled voltage source(VCVS). There is usually an additional input for...
