Abstract :
A 90 dBOmega optical receiver analog front-end (AFE), including a transimpedance amplifier, an automatic gain control circuit, and a post amplifier, is fabricated using a 0.18 mum CMOS technology. The receiver front-end provides a -3 dB bandwidth of 7.86 GHz and a GBW of 248.5 THz-Omega that exceeds the state of the arts. The photo current received by the receiver AFE is amplified to a differential voltage swing of 900 mVpp when driving 50 Omega output loads. The sensitivity of the optical receiver is -13 dBm at a bit error rate of 10 - 12 with a 231-1 PRBS test pattern
