Paper Abstract

The following technique compares GaAs monolithic processes regarding the requirement of transimpedance amplifiers to be used in optical front-ends. This technique uses a lumped element model of the forward amplifier to establish relationships between the small signal model of the devices which form the forward amplifier and the closed loop performance, as well as the root locus representation of the loop gain transfer function to set clear constraints to the frequency response. The comparison is performed by establishing a set of constraints to ensure the effectiveness of solution found and to reduce the number of degrees of freedom in this problem. This comparison has been carried out by taking into consideration the presence of the parasitic capacitance of the photodiode which plays an important role in the bandwidth performance.
