Abstract
A latch comparator which includes a preamplifier and a latch circuit. The preamplifier circuit operates amplification on a pair of differential input signals, and generates a pair of pre-amplified differential signals. The latch circuit receives the pre-amplified differential signals, compares the pair of pre-amplified differential signals, and generates a pair of latched comparison signals. The latch circuit includes a latch and a switch circuit. First and second input terminals of the latch receive the pre-amplified differential signals. The switch circuit includes a switch coupling between one of the first and second input terminals of the latch and the preamplifier circuit. The switch receives one of the pair of latched comparison signals as a control signal, and is switched in response to the one of the latched comparison signal.
