摘　　要：采用了 TSMC0 .3 5 μm CMOS工艺实现了可用于 SONET/SDH2 .5 Gb/s和 3 .12 5 Gb/s速率级光纤通信系统的限幅放大器。通过在芯片测试其最小输入动态范围可达 8m Vp- p,单端输出摆幅为 40 0 m Vp- p,功耗 2 5 0 m W,含信号丢失检测功能 。In this paper, a limiting amplifier was realized in TSMC 0 35μm CMOS technology for the use of 2 5Gb/s and 3 125Gb/s systems. Evaluated via on wafer testing, this limiting amplifier offers an input dynamic range of more than 40dB, provides a constant output of 400mV p-p and includes a module for detecting lost signals. Therefore, this limiting amplifier can meet the requirements of optical communication system.
