英文摘要	This paper presents a 65-nm CMOS 40-Gb/s PAM4 transmitter with power-efficient pre-emphasis. Switchable current sources are used in the pre-emphasis tap to eliminate power wasting. The pre-emphasis tap only injects current to the output nodes upon the voltage level transition of the output signal. Current does not flow through the pre-emphasis tap when there is no transition. Simulation results show that with insertion loss of the channel being 20.2 dB at 20 GHz, an eye height of 120 mV and an eye width of 30 ps are achieved. The driver consumes only 18.3 mW, which is equivalent to 0.46-pJ/b. ? 2014 IEEE.; EI; 0
