A 0.8-1.3V 16-channel 2.5Gbps High-speed Serial Transceiver in a 90nm Standard CMOS Process

摘要

We describe a 16-channel 2.5Gbps transceiver that operates off a single supply voltage ranging from 0.8V to 1.3 V. We fabricated the transceiver in a 90nm standard CMOS, using CMOS full-swing circuits except for a limited number of speed- and timing-critical circuits that were implemented in reduced-swing circuit topologies. The reduced-swing circuits were the last-stage 2:1 selector of the multiplexer, transmitter output driver, the decision latches, phase interpolators and delay cells in the VCOs. At a supply voltage of 0.8V, the power consumption of 16-channel transceiver is 362mW, i.e., 23mW per transceiver channel.
