摘要

提出了一种具有良好噪声性能的25Gb/s CMOS光接收机。完全集成的接收机包括一个跨阻放大器(TIA)、一个主放大器(MA)、辅助模拟环路和片上偏置电路。该接收机采用一种新颖的基于bjt的并联反馈TIA噪声优化技术，并结合增益和带宽提升方法实现低噪声。该接收机采用0.13μm SiGe BiCMOS技术设计和实现，旨在与商用光电二极管接口，具有最先进的输入参考噪声电流为1.66μArms，在消耗96mW的情况下显示78dB的跨阻增益和18.6GHz的带宽。

A 25Gb/s low-noise optical receiver in 0.13 μm SiGe BiCMOS

A 25Gb/s CMOS optical receiver with superior noise performance is presented. The fully integrated receiver comprises a transimpedance amplifier (TIA), a main amplifier (MA), auxiliary analog loops and on-chip bias circuitry. The receiver employs a novel noise optimization technique for BJT-based shunt-feedback TIA, together with gain and bandwidth boosting methods to achieve low noise. Designed and implemented in 0.13μm SiGe BiCMOS technology and intended to interface a commercial photodiode, the receiver demonstrates state-of-the-art input-referred noise current of 1.66μArms, reveals 78dB transimpedance gain and 18.6GHz bandwidth while consuming 96mW.
