Abstract :
This paper presents a new high performance wideband CMOS transimpedance amplifier (TIA) for 2.5 Gbps optical transceiver. Our proposed TIA self-regulating adjusts the controllable inductive peeking load and feedback resistances whenever overload condition occurs. The proposed TIA design exhibits bandwidth enhancement, lower input referred noise, and higher amplifier stability. This TIA has 69 dBOmega gain at 3 dB bandwidth, 7.2 pA/radicHz input referred noise and good performance of eye diagram. The TIA operates at the 3.3 V supply voltage, and dissipates about 34 mA for whole circuit. The simulation is accomplished with 1 pF capacitance and 0.85 A/W responsibility photodiode model
