Abstract
A differential capacitance detector comprising two pulse generators and a comparator. The width of each pulse generator output is representative of the capacity of each of two capacitors whose differential is to be determined. A comparator provides a third pulse whose width is the difference of the width of the pulses input from the pulse generators and is representative of the capacitance differential between the two capacitors.
