This article describes a circuit for sensing an analog reference voltage and storing it in digital form for later comparison to a sensed analog object voltage, also digitized for the comparison. The circuit is used for detecting copy paper that is unsuccessfully detached from contact with a photoconductor during operation of a copier machine.
