摘要

我们报告了一种跨阻放大器(TIA)的实现，该放大器使用并联反馈拓扑与调节级联输入级和宽带匹配网络的组合，采用0.13µm CMOS技术。所提出的TIA实现了7.5 GHz的3db带宽，在300 fF光电二极管电容存在下的跨阻增益为50 dBΩ，每个直流功率值的增益带宽乘积为578 GHzΩ/mW。

Design of transimpedance amplifier for optical receivers in 0.13 µm CMOS

We report the implementation of a transimpedance amplifier (TIA), using the combination of the shunt-feedback topology with the regulated-cascode input stage and broadband matching network, in a 0.13 µm CMOS technology. The proposed TIA achieves a 3-dB bandwidth of 7.5 GHz, transimpedance gain of 50 dBΩ in the presence of 300 fF photodiode capacitance, a gain-bandwidth product per DC power figure of merit of 578 GHzΩ/mW.
