Abstract
A Schmitt trigger voltage comparator circuit is provided including a voltage reference input, a current source having a first voltage controlled current source connected to the voltage reference input and a second voltage controlled current source connected to a signal input for converting the signal input to a input current and the voltage reference input to a reference current, a current mirror having an input connected to the output of the first voltage controlled current source configured and arranged to invert the direction of the first current and an output of the current mirror connected to the output of the second voltage controlled current source, and a sequence controller for generating digital signals to control a first plurality of switches and a second plurality of switches. The first plurality of switches control the first and second voltage controlled current sources and the second plurality of switches control the current mirror.
