Abstract :
Low-power/low-voltage applications and technology is becoming an increasingly important and growing area of electronics. This paper describes a new DC offset plus charge-injection compensation technique for high-performance CMOS or BiCMOS comparators working at low power supply. A very low-offset comparator has been implemented in a 1.5 μm CMOS process. It achieves a 500 ns comparison time @ 3.3 V with 100 μW or 100 ns @ 5 V with 1.25 mW. The die area is 0.1 mm2. The comparator sensitivity allows one to achieve >12-bit resolution in low-power integrated A/D converters
