Abstract
A receiver circuit and method for receiving a signal having a given carrier frequency. The circuit comprises: (1) a solar cell receiver having a selected capacitance and (2) an inductive device having a selected inductance and coupled to the solar cell receiver, the solar cell receiver and the inductive device cooperating to form a resonant circuit having a selected resonant frequency associated therewith and being a function of the selected capacitance and the selected inductance, the resonant circuit resonating in response to a change in the signal to thereby allow the solar cell to receive data carried by the signal. By employing solar cell as part of a resonant circuit, the range of optical remote controls can be extended to as much as a mile. In one embodiment, the receiver circuit forms a portion of a remote-controlled pool or spa.
