ABSTRACT:
A MOS comparator which exhibits a low offset transfer characteristic in spite of parameter variations during production, includes a biasing circuit which causes the transfer characteristics of the comparator stages to track the transfer characteristics of the output amplifier to which it is connected. Offset voltage caused by stage mismatch is thereby eliminated even though the amplifier and comparator are configured differently.
