Abstract
Provided are a StrongArm comparator and an SAR ADC. The StrongArm comparator includes an input module, a latch module, a first reset unit and a shunt unit. The input module is configured to receive a pair of differential input voltages, and the latch module is configured to generate a pair of differential output voltages. Operation of the first reset unit is controlled by a first clock signal, discharging of the coupling nodes of the input and latch modules through the input module is activated by an active pulse of the first clock signal, and discharging of the coupling nodes through the shunt unit is activated by an active pulse of a second clock signal, where a leading edge of the active pulse of the second clock signal lags behind the active pulse of the first clock signal, and trailing edges of the first and second clock signals end simultaneously.
