摘要

由于高速模拟集成电路的巨大需求，开发一种能在低功耗下工作的宽带低输入阻抗电流反射镜势在必行。本文提出了一种以低压级联电流镜(LVCCM)为基本模块的新型宽带低压高顺应电流镜。采用电阻补偿和感应调峰的方法来延长传统电流反射镜的带宽。通过将高遵从性电流镜中的传统LVCCM替换为补偿的LVCCM，在不增加直流功耗的情况下实现了3.4的带宽扩展比，并且不影响其其他性能。电路采用TSMC 0.18 μm CMOS工艺，在Spectre模拟器上设计。

Bandwidth Extension of High Compliance Current Mirror by Using Compensation Methods

Due to the huge demand of high-speed analog integrated circuits, it is essential to develop a wideband low input impedance current mirror that can be operated at low power supply. In this paper, a novel wideband low voltage high compliance current mirror using low voltage cascode current mirror (LVCCM) as a basic building block is proposed. The resistive compensation and inductive peaking methods have been used to extend the bandwidth of the conventional current mirror. By replacing conventional LVCCM in a high compliance current mirror with the compensated LVCCM, the bandwidth extension ratio of 3.4 has been achieved with no additional DC power dissipation and without affecting its other performances. The circuits are designed in TSMC 0.18 μm CMOS technology on Spectre simulator of Cadence.
