A Fully Differential Transconductance Amplifier
--EE240 final project, Spring
Department of Electrical Engineering and Computer Science
University of California at Berkeley, CA 94720
In this project, we design a fully-differential
operational transconductance amplifier to be used in the
first stage of a high resolution pipelined A/D converter.
The circuit is realized with a two-stage amplifier design.
The first stage is a telescopic cascode stage, followed by a
common source second stage. It’s demonstrated that this
circuit meets all the design specification while achieving
low power consumption, which is less than 10mW. This
OTA achieve a large DC gain and high swing output of
above 2.2V.
本项目中设计了一个全差分运跨导放大器，用于高分辨率pipeline A/D转换器的第一阶段。 该电路通过两级放大器设计实现。 第一级是折叠cascode，第二级共源级。实践证明，该电路符合所有设计规范，同时实现低功耗低于10mW。 |
