Abstract: Disclosed is a charge pump having first and second outputs and at least one capacitor. A plurality of switches are coupled to the at least one capacitor for selectively coupling the at least one capacitor between a high voltage node and a low voltage node, and for selectively coupling the at least one capacitor to the first output and the second output. A switch controller is adapted to generate control signals for the plurality of switches to selectively couple the at least one capacitor between the high voltage node and the low voltage node during charging, and to selectively couple the at least one capacitor to the first output and the second output during discharging that output a first voltage pulse from the first output and a second voltage pulse from the second output such that the first voltage pulse and the second voltage pulse are asymmetrical and coincidental.

Abstract: An exemplary embodiment of an analog multiplier may include a voltage controlled resistance circuit, a first transistor and a second transistor, where the resistance of the voltage controlled resistance circuit is based upon a difference between a supply voltage and a first input voltage and a constant current supply. The current passing through the voltage controlled resistance circuit is based upon a difference between the voltage supply and a second input voltage. The first transistor may be configured to mirror the current passing through the voltage controlled resistance circuit.
