Since operational transconductance amplifiers (OTAs) form the basic building blocks of
many analog systems, the compensation of three-stage OTAs has attracted a lot of attention …

This review is aimed at the integrated circuit design community and it explores slew-rate
enhancement techniques for switched-capacitor amplifiers, with a primary focus on …

A novel approach to design low-power area-efficient rail-to-rail output single-stage class-AB
operational transconductance amplifiers (OTAs) with enhanced large-and small-signal …

This paper introduces a new effective single-Miller capacitor compensation topology for
three-stage amplifiers with very large capacitive loads, realized through an active-feedback …

In this study, a local positive feedback technique is proposed to enhance the performance of
the folded cascode (FC) operational transconductance amplifier (OTA) when working in its …

This brief presents a low-power, area-efficient three-stage CMOS operational
transconductance amplifier (OTA) suitable for very large capacitive loads, C L. A single …

An adaptively biased low-dropout regulator (AB-LDO) with current mirror buffer has been
proposed in previous literatures, which only solves a few of the specific problems of AB-LDO …

A low-power fully-integrated analog front end for biopotential sensors is proposed. The
signal conditioning circuitry features an integrating sampler and a digital-assisted electrode …

Multistage amplifiers are a reliable method of achieving high gain in systems where the
voltage supply is low. The common practice is to prefer 3-stage amplifiers over 4-stage ones …

With the existing circuit topologies, the conventional multi-stage amplifiers (MSA) can only
achieve low gain-bandwidths (<; 5 MHz) and low slew rates (<; 10 V/μs). These …
