Zero crossing detector


Posted on Jun 2, 2012

This detector is useful in sine wave squaring circuits and A/D converters. The positive input may either be grounded or con-output nected a nulling voltage which cancels input offsets and enables accuracy to within microvolts of ground

The CMOS output will switch to within a few millivolts of either rail for an input voltage change of less than 200 µV.
