Abstract:
    An analog-to-digital converter includes an amplifying unit and a noise compensation unit. The amplifying unit amplifies a difference between a trip point voltage and a modified signal voltage. The trip point voltage has a first power noise component, and the noise compensation unit incorporates a second power noise component into an original signal voltage to generate the modified signal voltage. Thus, the power noise components are cancelled in the difference.
