Abstract :
A photoreceiver post-amplifier circuit based on a transconductance-transimpedance cascade is presented which meets the specific performance requirements of dense photoreceiver arrays comprising hundreds of high bit rate channels. Simulations of 1 Gbit/s receivers show an improvement in sensitivity, at some cost in layout area, over previous circuits based on low-gain voltage amplifiers
