Abstract

An integrated circuit on a chip may include a plurality of capacitors that are connected in series and generate an AC noise signal. A selected bandwidth of the AC noise signal transmits through the series of capacitors as a first AC power signal. Respective rectifiers are positioned for receiving a positive cycle of the first AC power signal and a negative cycle of the first AC power signal. Output terminals are connected to the respective rectifiers and configured for connection to an off chip circuit. The capacitors may be fixed or variable gap capacitors.
