Inductorless CMOS Receiver Front-End Circuits for 10-Gb/s Optical Communications

[[abstract]]In this paper, a 10-Gb/s inductorless CMOS receiver front end is presented, including a transimpedance amplifier and a limiting amplifier. The transimpedance amplifier incorporates Regulated Cascode (RGC), active-inductor peaking, and intersecting active feedback circuits to achieve a transimpedance gain of 56 dB and a bandwidth of 8.27 GHz with a power dissipation of 35 mW. The limiting amplifier employs interleaving active feedback to achieve a differential voltage gain of 44.5 dB and a bandwidth of 10.3 GHz while consuming 226 mW. Both circuits are realized in 0.18- m CMOS technology with a 1.8-V supply.[[notice]]補正完畢[[incitationindex]]EI[[booktype]]紙
