A low power 5Gb/s transimpedance amplifier with dual feedback technique

Abstract

This paper presents the design and implementation of a 5Gb/s transimpedance amplifier (TIA) with dual shunt-shunt feedback technique to enhance the circuit performance. Measured bandwidth is 4.9GHz and measured transimpedance gain is 60 dB /spl Omega/. The chip consumes only 8mW at 1.8V supply voltage and occupies 650 /spl mu/m /spl times/ 500 /spl mu/m in a 0.18 /spl mu/m CMOS process.
