Abstract :
A 36-Gbps transceiver with a continuous-time linear equalizer and a 1-tap DFE in 20-nm CMOS is demonstrated. The transceiver uses a quarter-rate (i.e., 9-GHz) differential-clock distribution to reduce the clock-delivery power. Multi-phase half-rate clock signals that drive the transceiver front-ends are generated by a delay-locked loop and frequency doublers that systematically reduce the impact of skew and jitter. The transceiver occupies 0.55 mm2 and consumes 609.9 mW of power from a 0.9-V supply.
