A High Speed GaAs Monolithic Transimpedance Amplifier

Abstract

This paper describes the design method and test results for a novel transimpedance amplifier suitable for very high speed optical communications systems The amplifier chip is developed for four different bit rates: 188, 565, 1130, and 1500 Mb/s with optical sensitivities -38.5, -33, -30, dBm, respectively. The amplifier provides 2 V peak to peak output and 30 dB dynamic range.
