Computer-aided design and GaAs realizations of 4.8 and 9.6 Gbit/s optical receivers

Up until now the simplified "real frequency" technique has been applied to the design of broadband multistage microwave amplifiers where gain and VSWR are optimized, In this paper we extend the method to the design of transimpedance amplifier for a wide band optical receiver . So the noise is optimized in parallel with the gain and VSWR. The synthesis of the networks (equalizer) is carried out in two ways, with lumped elements arid distributed elements. Then we give several examples of design ; transimpedance amplifier and ultra wide band GaAs amplifier.
