ABSTRACT:
A MOS hysteresis comparator having a source transistor bias circuit which generates a source current Is that compensates for temperature and manufacturing process variations, thereby providing a hysteresis characteristic which is substantially insensitive to such temperature and manufacturing process variations. The source transistor bias circuit includes a set of MOS transistors which replicate the comparator load currents which occur at the switch points of the comparator, and a source transistor which mirrors the sum of the replicated currents to form the source current Is of the comparator.
