Abstract

A high transimpedance-bandwidth, high dynamic range, integrated CMOS amplifier is presented. This front-end circuit is specially designed for open air optical communications featuring a 50 MHz bandwidth with a dynamic range of 60 dB, due to the implemented automatic step gain control. The power consumption is around 70 mW and the input referred noise is smaller than 36 pA_rms. The design approach is full custom based, using a double poly, double metal, 0.8 μm CMOS technology
