Abstract

This paper presents a new voltage comparator design called Quantum Voltage (QV) comparator for the next generation deep sub-micron low voltage CMOS flash A/D converter (ADC). Unlike the traditional differential voltage comparators designed to minimize input-offset voltage error due to the mismatches in a differential transistor pair the QV comparators are designed to optimize the input-offset voltages by systematically and uniformly varying the transistor sizes of the differential transistor pair. The QV comparators allow very small voltage comparison, complete elimination of resistor ladder circuit, and dramatic improvement of linearity in an ADC.
