COMPARATOR CIRCUIT FOR REDUCED OUTPUT VARIATION

摘要

A comparator circuit for generating a signal representing a comparison of an input signal and a reference signal. In an embodiment, the comparator circuit includes a first stage and a second stage to provide respective signal amplification, where switch circuitry of the second stage switchedly couples respective elements of the first and second stages. The comparator circuit further includes a third stage to generate an output signal based on an intermediate signal of the second stage. In another embodiment, feedback circuitry of the comparator circuit is to selectively control a voltage of the output stage based on the output signal.
