Abstract

In this paper, a low-noise differential transimpedance amplifier (TIA) for 10 Gbit/s fiber links is presented. The TIA is optimized for the best phase linearity over the bandwidth resulted in a group delay variation less than 1 ps. The circuit is designed with 0.35 μm SiGe heterojunction bipolar transistor BICMOS process. 9 GHz bandwidth, almost 58 dBΩ transimpedance gain with less than 11 pA√Hz input-referred noise current are achieved. The power consumption is 71 mW.
