Abstract
A system and method for providing power to a light-powered transponder. In order to create a sufficient voltage differential, two different photovoltaic elements are used. The photovoltaic elements generate voltages of different polarities. Because the photovoltaic elements are used independently to generate voltages with different polarities, the present system can achieve a desired voltage differential despite the inherent difficulties presented by the use of a standard CMOS process.
