Abstract
A comparator circuit, including an input circuit, first and second inverting amplification circuits, first and second coupling circuits, and a feedback circuit, wherein the input circuit generates an amplified input signal based on positive and negative input voltages, the first inverting amplification circuit generates an intermediate amplified signal based on the amplified input signal during a sampling period, the second inverting amplification circuit generates a comparison result signal based on the intermediate amplified signal during the sampling period, the first coupling circuit is connected between the input circuit and the first inverting amplification circuit, the second coupling circuit is connected between the first inverting amplification circuit and the second inverting amplification circuit, and the feedback circuit amplifies the input node of the first inverting amplification circuit with a rail-to-rail voltage corresponding to a power supply voltage or a ground voltage based on the comparison result signal during the sampling period.
