摘要

本文介绍了一种具有规定输入和输出阻抗的新型CMOS电流放大器。该电路使用一个反向连接的改进电流输送机。给出了输入阻抗、电流增益和输出阻抗的计算方法。最苛刻的设计参数是输入阻抗:在电流增益或输出阻抗恶化之前，它有一个电感元件迫使该阻抗随频率增加。通过仿真验证了计算结果。

A CMOS current amplifier having prescribed input and output impedance

The paper describes a new CMOS current amplifier with prescribed input and output impedance. The circuit uses an inverse connection of a modified current conveyor. The calculation of input impedance, current gain and output impedance is given. The most demanding design parameter is the input impedance: it has an inductive component forcing this impedance to increase with frequency long before the current gain or output impedance deteriorates. The results of calculations are verified with simulations.
