摘要

利用TSMC 0.18μm CMOS工艺设计了应用于SDH系统STM-64(10 Gb/s)速率级光接收机中的限幅放大器.该放大器采用了改进的Cherry-Hooper结构以获得高的增益带宽积

从而保证限幅放大器在10Gb/s以及更高的速率上工作.测试结果表明

此限幅放大器在10Gb/s速率上

输入动态范围为42dB(3.2mV~500mV)

50Ω负载上的输出限幅在250mV

小信号输入时的最高工作速率为12Gb/s.限幅放大器采用1.8 V电源供电

功耗110mW.芯片的面积为0.7mm×0.9mm.

Abstract

A 10Gb/s limiting amplifier for SDH STM-64 optical receiver is realized in 0.18μm CMOS technology.A modified Cherry

Hooper architecture is employed to achieve a higher gain-bandwidth product.The measured results demonstrate an input dynamic range of 42dB (3.2mV~500mV) with constant output swing 250mV.The highest bit rate can be achieved is up to 12Gb/s with a small-signal input.The power dissipation is 110mW with the supply voltage of 1.8V.The chip area is 0.7mm×0.9mm.
