Integrated circuit combination of a target integrated circuit, photovoltaic cells and light sensitive diodes connected to enable a self-sufficient light detector device

Abstract

An integrated circuit (IC) comprises a plurality of photovoltaic (PV) cells formed over a passivation layer of a target integrated circuit (TIC), wherein at least one PV cell of the plurality of PV cells is usable as a light sensing device; an interface to an energy storage unit; the TIC comprising at least: a control unit; and a switching circuit, the switching circuit coupled to the plurality of PV cells, the energy storage, and the control unit; wherein the control unit is configured to control at least the switching circuit to configure a connection scheme, wherein the connection scheme devises at least one first PV cell of the plurality of PV cells to connect to the energy storage and at least one second PV cell to connect to the control unit for light detection.
