A 40 Gbps optical receiver analog front end integrating a trans-impedance amplifier (TIA) and a limiting amplifier is presented. To achieve wide band operation, nested feedback TIA and interleaving post amplifier with split series-peaking are proposed in this design. This receiver provides the transimpedance of 92 dBOhm, input-referred noise of 14 pA/Hz, 3dB bandwidth of 35 GHz, and 800mV pp differential output voltage swing. The total power dissipation is 168 mW from 1.2-V supply. Fabricated in a 65 nm CMOS technology, the chip size is 0.825mm 2.
