Design analyst of low energy, high gm/Id, and high sensitivity comparator

Abstract

This paper analyses three innovative designs of comparators and those structures have better performance than the traditional comparator. The dynamic floating inverter amplifier improves energy efficiency by preventing full discharging and charging. The Dynamic Bias Latch-Type Comparator used a double-tails latch to decrease energy consumption. The charge-injection compensations comparator has better sensitivity and less noise by utilizing the feedback loop. Those methods have greatly increased voltage gain, energy efficiency, and gm/Id
