Abstract

The effects of layout parameters on the gain response speed noise behaviour and sensitivity of a hybrid optical receiver consisting of a three stage GaAs monolithic transimpedance amplifier and a detector using SPICE has been analysed. The BFL type configuration consisting of an inverter and buffer/level shift circuit was chosen for the amplifier design. The simulated results predict the optimised layout parameters for the targeted gain of 100 with 300 Mbit/Sec data rate and 40 dBm sensitivity for CEERI''s 1/um gate length GaAs MESFET technology.
