Abstract
A latch device includes a differential pair, a differential circuit, and a clock gate circuit. The differential pair receives differential input signals, and the differential circuit performs a logic operation on the differential input signals. The clock gate circuit is configured to supply a supply voltage from the power supply node to the first connection node according to a clock signal. The clock gate circuit includes a reference-independent circuit and a reference-dependent circuit. The reference-independent circuit is configured to control a first electrical path between the power supply node and the first connection node according to the clock signal. The reference-dependent circuit is configured to control a second electrical path between the power supply node and the first connection node according to the clock signal and a first control signal, wherein the first control signal is determined according to a voltage level of one of the differential input signals.
