Abstract :
A high-speed transimpedance amplifier (TIA) has been designed and implemented in a low cost 0.35 mum CMOS technology. Combining the techniques of regulated cascode input stage, current shunt feedback and inductive-series peaking, the TIA achieves a transimpedance gain of 51 dBOmega and 3 dB bandwidth of 6 GHz, in the presence of a photodiode capacitance of 0.6 pF. This is believed to be the fastest TIA ever reported in 0.35 mum CMOS technology
