저전압 저전력 비교기 설계기법
Low-voltage low-power comparator design techniques
초록
A CMOS comparator is designed for low voltage and low power operations. The proposed comparator consists of a preadmplifier followed by a regenerative latch. The preasmplifier reduces the power consumption to a half with the power-down mode and the dynamic offsets of the latch, which is affected by each device mismatch, is statistically analyzed. The circuit is designed and simulated using a 0.8.mu.m n-well CMOS process and the dissipated power is 0.16mW at a 20MHz clock speed based on a 3V supply.
