摘要

提出了一种全新的用于光纤接收机的CMOS透阻前置放大器拓扑结构。它是基于共门拓扑结构，用负反馈来增加电路的带宽。实现了2.7 GHz的带宽，并具有重要的降噪效果。得到了载波下42 dB的互调产物。采用HSPICE和Spectre-CADENCE软件的BSIM3v3模型进行仿真。

A new transimpedance preamplifier topology for high-frequency applications

A fully new CMOS transimpedance preamplifier topology 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 2.7 GHz, with important noise reduction, was achieved. Intermodulation products of 42 dB below the carrier were obtained. Simulations were performed using BSIM3v3 models for HSPICE and Spectre-CADENCE software.
