Abstract
A comparator amplifier circuit is integrated in MOS form. A sense amplifier section is coupled to a buffer amplifier section to provide an output that changes sharply at a particular voltage input. A compensating amplifier section is coupled between the comparator amplifier and a node in the buffer amplifier so that the voltage sense is independent of integrated circuit manufacturing variables.
