Abstract
The effect of shunt-shunt feedback in monolithic transimpedance amplifiers for multiGbit per second optical receivers on the input impedance is considered in this paper. The main transfer function to be optimized is the transimpedance, but the input impedance should be taken into careful consideration to avoid unexpected peaking effects which can be a cause of performance degradation. The interconnection technique used to couple the photodiode to the MMIC amplifier has to be properly chosen in conjunction with the performance of the amplifier as current sink at the input port. We propose a design methodology based on the root-locus technique which can help the designer in the optimization of this kind of circuit with particular regard to the input peaking effects.
