An 8-b pipelined ADC constructed in 0.13-lm CMOS is described. This ADC uses a dual-supply technique to yield 8-b performance at a sampling rate of 125 MS/s while consuming 30 mW from 1.8-V and 1.2-V supplies. Active area is 0.4 mm 2 . Numerous challenges associated with this choice of process technology were overcome, such as limited dynamic range, copper metallization and the effects of gate oxide leakage.
