Abstract
In this paper the analysis for bandwidth extension of Transimpedance amplifiers using inductive feedback based on the characteristics of complex conjugate poles has been done in details. The circuit achieves a 3-dB bandwidth of around 30GHz in the presence of a 50fF photodiode capacitance and 5fF loading capacitance while only dissipating 2.2mW. Also noise performance is competitive in comparison with state of the art.
