Abstract :
A monolithic 8-bit flash A/D converter is described which digitizes a 40-MHz signal at a conversion rate of over 100 MHz. To obtain full resolution and high accuracy at ultrahigh speed operation, a three-stage comparator with small talk back and other new logic circuits were designed. The process used is a self-aligned bipolar technology. Signal-to-noise ratio of 45 dB was measured at the 30-MHz input frequency.
