Abstract :
A 6-b Nyquist A/D converter (ADC) that converts at 1.3 GHz is reported. Using array averaging and a wideband track-and-hold, a 6-b flash ADC achieves better than 5.5 effective bits for input frequencies up to 630 MHz at 1 Gsample/s, and five effective bits for 650-MHz input at 1.3 Gsample/s. Peak INL and DNL are less than 0.35 LSB and 0.2 LSB, respectively. This ADC consumes about 500 mW from 3.3 V at 1Gsample/s. The chip occupies 0.8-mm2 active area, fabricated in 0.35-μm CMOS
