Abstract :
A 10b 205MS/S IF sampling pipelined ADC is fabricated in 1.2/3.3V 0.13μm CMOS. Power consumption and die area are improved by using single-stage opamps throughout the pipeline chain; digital calibration compensates for the reduced stage gain. Foreground calibration is used to shorten the start-up time and background calibration is used afterwards. The ADC has ENOB of 9.0, ERBW of 330MHz, dissipates 92.5mW, and occupies 0.52mm2.
