When applied to folding ADCs, pipelining relieves the wide bandwidth requirement of the folding amplifier. A pipelined folding ADC prototyped using a 0.5 /spl mu/m CMOS process exhibits a DNL of /spl plusmn/0.4 LSB and an INL of /spl plusmn/1.3 LSB at 100 MSample/s. The chip occupies 1.4 mm/spl times/1.2 mm in active area and consumes 165 mW at 5 V.
