摘要

提出了一种全新的用于光纤接收机的CMOS差分透阻前置放大器结构。它是基于带负反馈的共门拓扑，以增加电路的带宽。实现了2.30 GHz的带宽，并具有重要的降噪效果。得到了载波下40 dB的互调产物。采用HSPICE的BSIM3v3模型进行仿真。

Differential transimpedance amplifiers for communications systems based on common-gate topology

A fully new CMOS differential transimpedance preamplifier structure for fiber optics receivers is presented. It is based on the common-gate topology with negative feedback, to increase the bandwidth of the circuit. A bandwidth of 2.30 GHz, with important noise reduction, was achieved. Intermodulation products of 40 dB below the carrier were obtained. Simulations were performed using BSIM3v3 models for HSPICE.
