Abstract
A comparator includes: a first stage circuit, configured to receive a voltage signal to be compared and a reference voltage signal Vref, and to generate and output a first amplifying signal and a second amplifying signal based on the voltage signal to be compared and the reference voltage signal Vref; a second stage circuit, connected with the first stage circuit, configured to generate and latch a first output signal and a second output signal based on the first amplifying signal and the second amplifying signal; wherein the first stage circuit and/or the second stage circuit include(s) a first pair of cross-coupled transistors.
