摘要

文章提出了一种速率为622 Mb it/s的带自动增益控制（AGC）和自动偏移补偿（AOC）的光通信用跨阻集成放大器电路。本设计采用了中芯国际0.25μm 1P3M的标准互补金属氧化物半导体（CMOS）工艺。HSPICE仿真结果表明

在各种偏差最大的工艺条件下

跨阻放大器初始增益的浮动区间为-10.2%

.7%

而AGC的初始偏置电压的浮动区间为-0.384%

.307%。

Abstract

A 622 Mbit/s TIA integrated circuit with AGC and AOC for optical communications is proposed.SMIC 0.25 μm 1P3M CMOS process is applied in the design.HSPICE simulation shows that in all the worst cases

the floating region of TIA initial gain is between-10.2% and 9.7%

and the floating region of initial AGC bias voltage between-0.384% and 0.307%.
