Abstract :
This paper presents an improved low-voltage low-power CMOS comparator suitable for high-speed pipeline ADCs. Simulated results of the proposed circuit in a 0.35 μm standard CMOS technology operating at supply voltages within the range of 1.0-1.5 V show that this comparator achieves low offset, reduced kickback noise, high mean-time to failure and exhibits low-power dissipation at very high-speed operation.
