This paper presents a 65-nm CMOS, 1-V, 1.37-pJ/bit optical receiver with embedded equalizer, enabling adaptability to overcome channel losses and component variations. The digitally-controlled continuous-time linear equalizer (CTLE) consists of three cascaded tunable peaking stages offering 16-dB of adjustable low-frequency gain. Optical measurement results with a 30-Gb/s photodetector (PD) show that the receiver achieves 10-12 BER at 30 Gb/s for a 215-1 PRBS input with a -5.6-dBm input sensitivity. Using a lower bandwidth 14-Gb/s PD, the receiver can still reach 30 Gb/s at 10-12 BER with only a 0.6-dB degradation in input sensitivity. These measurement results demonstrate the effectiveness of the proposed receiver and the programmable cascaded CTLE. |
