Abstract

A capacitor divider includes two capacitors coupled in series between two voltage sources. A first capacitor is a floating gate capacitor having one plate being the control gate of a floating gate transistor structure and the other plate being a source, drain, and channel region of the floating gate transistor structure. The capacitive divider has the advantage of having at least one floating gate capacitor, can be implemented in a voltage regulator, and works for a variety of voltages across the capacitors.
