The new architectures of the high-speed operational amplifier (op-amp) based on the
complementary folded cascodes (FCs), which form the intermediate stage of op-amp, are …

In this paper we extend the figures of merit for class AB symmetrical OTAs to the fully
differential case and compare topologies from the literature. This analysis shows that the …

The features of operation of the micropower CMOS operational amplifiers (Op-Amp) with a
dual-input-stage (DIS) in the large-signal operation are considered. It is shown that due to …

The article considers a method of increasing the maximum slew rate (SR) of BiJFets Op-Amp
with one-pole frequency compensation, the input stage of which operates in the microcurrent …

This paper presents a new class-AB pseudo-differential operational transconductance
amplifier (OTA) for low-voltage and high-speed switched-capacitor circuits. The proposed …

Based on a previously reported low voltage class-AB CMOS linear transconductor, we
propose a simple technique to modify such a circuit so that its transconductance gain is …

The paper suggests an novel architecture of the operational amplifier (OA) using the circuit
method to increase the high-speed response. It is provided due to special circuit of nonlinear …

A Sigma-Delta (SigmaDelta) modulator with 10 bits of resolution and only 55 nW power
consumption for electroencephalogram (EEG) applications is presented. The overall …

A Sigma-Delta (ΣΔ) modulator with 8 bits of resolution and only 330 nW power consumption
for a cardiac pacemaker is presented The overall modulator operates from 2.3 V down to 1.5 …

New architecture and circuit solutions of arsenide-gallium operational amplifiers (Op-Amps)
for GaAs JFET/BJT combined processes are considered. We propose a family GaAs of Op …
