摘要

本文介绍了一种用于差动对的低压电流反射镜作为主动负载。该电流反射镜具有高输出阻抗和低输入阻抗的特点，工作电压为±0.5 V。所提出的结构采用了PMOS晶体管的电压电平移位原理。通过在该结构上使用块电压，实现了电压电平移位操作。仿真结果表明，在输入电流为200 μA的情况下，采用外置电容设计的电流反射镜具有良好的性能，带宽为11 GHz。

A Low-Voltage Current Mirror for Transconductance Amplifiers

In this study, a low-voltage current mirror to use in differential pair as an active load is introduced. The proposed current mirror which can operate at ±0.5 V has high output impedance and low input impedance. The proposed structure employs the principle of the voltage level-shifting for PMOS transistors. The voltage level-shifting operation has been achieved by using bulk voltage at this structure. Also, spice simulations justify the highly good performance of this current mirror with a bandwidth of 11 GHz by using external capacitor at input current of 200 μA.
