Super class AB-AB bulk-driven folded cascode OTA

Integration, 2018
Abstract A super class AB-AB bulk-driven folded cascode operational transconductance amplifier (OTA) with improved slew rate and unity-gain bandwidth is presented. The proposed bulk-driven amplifier utilizes the adaptively biased circuits, the bulk-driven flipped voltage follower and quasi-floating gate circuit, to implement the class-AB input stage ...

Class-AB Power Amplifier Design Guidelines

SBMO International Microwave Conference/Brazil,, 2005
The design of high-power high-efficiency narrowband amplifiers implies a carefull choice of bias point, loading and power level. The choice of class A, AB, B, or C is based on a compromise between gain , output power, efficiency and total and/or specific distortion content[1].

Gain and Bandwidth Enhanced Class-AB OTAs

2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS), 2019
Efficient class-AB OTAs with enhanced gain bandwidth, open loop gain, output current, and slew rate are presented. They are based on a g m -boosting technique (at least factor of two) and also use dynamically biased cascode transistors to achieve high gain and output currents much larger than the bias current.

CMOS latch based on a class-AB transconductor

2011 20th European Conference on Circuit Theory and Design (ECCTD), 2011
In this paper a novel CMOS latch is designed using a class-AB transconductor as a core. The static latch behavior is studied using a homotopy method which allows highlighting sufficient conditions for the transconductor to become a latch. These last conditions are general and can be used for the design of new latches and comparators. The proposed latch

A class of ABS algorithms for Diophantine linear systems

Numerische Mathematik, 2001
An approach is proposed, based on Abaffy-Broyden-Spedicato methods (ABS), for solving the linear Diophantine vector equation \(Ax=b\), where \(A\in\mathbb{Z}^{m\times n}(m\leq n)\), \(b\in\mathbb{Z}^m\), \(x\in\mathbb{Z}^n\) is the solution and \(\mathbb{Z}\) is the set of integers.

Figures of merit for class AB input stages

2011 20th European Conference on Circuit Theory and Design (ECCTD), 2011
Three representative class AB Current Mirror OTAs are analytically compared in term of the trade-off speed, current consumption and area. The approach presented allows to derive useful design guidelines. The analysis was validated by means of simulations considering a 90 nm CMOS technology.

A high performance class AB current conveyor

1998 IEEE International Conference on Electronics, Circuits and Systems. Surfing the Waves of Science and Technology (Cat. No.98EX196), 2002
A class AB CMOS current conveyor is developed for wideband current-mode signal processing, It consists of a differential stage for the voltage input, a single-ended push-pull stage for the current input, and current mirrors for the current output. The differential and push-pull stages form a unity-gain buffer, to realize exact voltage-following action ...

Class AB CMOS amplifiers with high efficiency

IEEE Journal of Solid-State Circuits, 1990
A new class AB CMOS operational-amplifier principle is presented. A transconductance amplifier based on this principle exhibits small-signal characteristics comparable to those of a conventional OTA. It has, however, a superior current efficiency and its settling time is not slew-rate limited.

Class-AB current conveyors based on the FVF

2017 European Conference on Circuit Theory and Design (ECCTD), 2017
We propose a novel class-AB second-generation Current Conveyor (CCII) based on the class-AB Flipped Voltage Follower (FVF) topology, and compare it with a class-A CCII based on the conventional FVF. The AB-FVF is capable of driving larger capacitive loads, showing faster settling.
