Abstract

A novel broadband low-noise transimpedance amplifier (TIA) with automatic gain control (AGC) is designed with 0.18 μm 1.8 V RFCMOS technology for the application in 10 GB/s fiber-optical data links. Post-layout simulation of the proposed design shows a -3 dB bandwidth of 9.1 GHz with an adaptive transimpedance gain of 490 Ω in the weak-input case and 170 Ω under input overload condition.
