Design Optimization of a Transimpedance Amplifier for a Fiber Optic Receiver

Abstract

This paper presents the design of a framework for the optimization of a low-power, low-noise, broadband transimpedance amplifier to be used in a fiber optic transceiver. The design is implemented using a 180 nm six-metal-layer digital CMOS process with a 1.8V supply. The performances achieved are a gain of $$78.34\,\hbox { dB}\Omega $$78.34dBΩ, a bandwidth of 2.21 GHz, an input referred current noise of $$11.91\,\hbox { pA/Hz}^{1/2}$$11.91pA/Hz1/2, and a power dissipation of 13.5 mW.
