Abstract
A rail-to-rail comparator circuit includes NMOS and PMOS differential input stages with associated loads that are coupled to a shared-load stage. The shared-load stage is coupled to an output stage that includes two active devices. By sharing the load stage between the two input stages, the comparator has a relatively small circuit area, low power draw, and low propagation delay with rail-to-rail input common-mode voltage range.
