Abstract
A comparator based on a pre-amplifier stage structure and an analog-to-digital converter are provided. The comparator includes: a first pre-amplifier stage, where an input terminal of the first pre-amplifier stage is connected to a differential input signal, to amplify and output the differential input signal so as to output a first differential output signal; a second pre-amplifier stage, where an input terminal of the second pre-amplifier stage is connected to the first differential output signal, to amplify and output the first differential output signal so as to output a second differential output signal, and a positive feedback unit is disposed between an output terminal of the second pre-amplifier stage and the input terminal of the second pre-amplifier stage, to increase a voltage gain of the second pre-amplifier stage by using the positive feedback unit; and a latch, an input terminal thereof connected to the second differential output signal.
