摘要

This paper presents a low-power high-speed CMOS signalingninterface that operates off of an adaptively regulated supply. Anfeedback loop adjusts the supply voltage on a chain of inverters untilnthe delay through the chain is equal to half of the input period. Thisnvoltage is then distributed to the I/O subsystem through an efficientnswitching power-supply regulator. Dynamically scaling the supply withnrespect to frequency leads to a simple and robust design consistingnmostly of digital CMOS gates, while enabling maximum energy efficiency.nThe interface utilizes high-impedance drivers for operation across anwide range of voltages and frequencies, a dual-loop delay-locked loopnfor accurate timing recovery, and an input receiver whose bandwidthntracks with the I/O frequency to filter out high-frequency noise. Testnchips fabricated in a 0.35-Μm CMOS technology achieve transfer ratesnof 0.2-1.0 Gb/s/pin with a regulated supply ranging from 1.3-3.2 V
