Claim Text:
1. An integrated circuit (IC), comprising: a plurality of photovoltaic (PV) cells formed over a passivation layer of a target integrated circuit (TIC); and an interface adapted to be coupled to an energy storage unit; the TIC comprising at least: wherein the control unit, when operating, is configured to control at least the switching circuit to couple at least one first PV cell of the plurality of PV cells to the energy storage unit, wherein energy generated by the at least one first PV cell of the plurality of PV cells is stored in the energy storage unit, and to couple at least one second PV cell of the plurality of PV cells to the control unit, wherein the control unit is configured to employ energy generated by the at least one second PV cell of the plurality of PV cells for determining a characteristic of light incident on the at least one second PV cell of the plurality of PV cells.
