ABSTRACT:
A CMOS comparator circuit is disclosed in which a low offset is achieved without trimming. The input stage is composed of a pair of bipolar transistors which have lateral non-dedicated collectors that operate in parallel with the substrate dedicated collectors. The input stage includes matched load devices and is followed by an amplifier having a differential to single ended converter.
