Popis:	A 4-bit 12-GSample/sec A/D converter (GAD) has been fabricated in a 0.25-/spl mu/m CMOS process to investigate the design of an equalized multi-level link. Clocked differential amplifiers were used to sample the input, followed by high-speed comparators with current-summed offset cancellation. Input bandwidth was measured at 2.5 GHz. Eight 1.5-GSample/sec flash A/D converters were interleaved to achieve the aggregate sample rate.
