摘要

本文提出了一种改进的标准自动调零(AZ)放大器拓扑结构，它需要更少的芯片面积来实现高偏移性能。为了改善电荷注入对剩余偏置电压的影响，在信号路径和偏置补偿环路之间实现了高增益比。这种设计的新颖之处在于使用了不同的两个输入对拓扑。

An area efficient low offset autozero amplifier design

This paper presents a modification of the standard autozero (AZ) amplifier topology that requires less chip area for achieving high offset performances. To improve the charge injection effects on the residual offset voltage a high gain ratio between the signal path and offset compensation loop is implemented. The novelty of this design consists in the different two input pair topologies used.
