摘要

本文介绍了一种基本的电流放大器模块，定义了其性能参数，并介绍了一些优化设计方法。采用32nm CMOS技术设计和比较了几个版本的放大器。比较的目的是研究降低输入阻抗的不同方法如何影响放大器的其他参数:带宽、输出阻抗、非线性。

Design Approaches for Reducing the Input Impedance of CMOS Current Amplifier

This paper presents a basic current amplifier block, defines its performance parameters and describes some design approaches to optimize them. Several versions of the amplifier are designed and compared using 32nm CMOS technology. The goal of the comparison is to study how different approaches for reducing of the input impedance affects the other amplifier parameters: bandwidth, output impedance, nonlinearity.
