A method and circuit for setting a reference voltage in a dual floating gate circuit is disclosed. During a set mode, a first and second floating gate are programmed to different charge levels that are a function of an input set voltage capacitively coupled to the first floating gate during the set mode. During a read mode, this difference in charge level is is used by the dual floating gate circuit to generate a reference voltage that is a function of the input set voltage, and is preferably equal to the input set voltage.
