Abstract :
A bandwidth enhancement technique for a resistive shunt-feedback transimpedance amplifier (TIA) is developed in this paper. The technique relies upon a π-peaking network realization using the shunt-feedback TIA as part of the network in order to offer a high bandwidth while maintaining a low noise performance. The output is obtained by making use of subsequent amplifier stages with the non-uniform constant-k output network for simultaneously high gain and bandwidth. Practical performance verification was provided via the design and simulation of a 50 dB·O 10-GHz π-peaking TIA, where it clearly exhibits a superior bandwidth over the conventional TIA.
