Power circuit and method

An electronic device comprising:

• a transformer having a first coil, and a second coil;
• an additional transformer having an additional first coil, and an additional second coil;
• an antenna connected in a parallel configuration to the first coil and the additional first coil;
• wherein the second coil and the additional second coil are connected in series to yield a charging node, wherein a rectifier is operably connected to the charging node, and wherein a power storage device is operably connected to a set of output terminals of the rectifier.

A method of charging a power storage device comprising the steps of:

• placing the electronic device in an environment that is exposed to electromagnetic radiation;
• sensing at least a portion of the electromagnetic radiation with an antenna that is operably associated with the electronic device;
• transferring an incremental amount of electrical power from the antenna into a first coil of at least one inductive element;
• transforming the incremental amount of electrical power into an incremental voltage difference across a second coil of the at least one inductive element;
• accumulating a plurality of incremental voltage differences across a plurality of second coils that are connected in series to yield a charging voltage difference;
• transmitting the charging voltage difference to a set of input terminals of a rectifier;
• using a charging current from a set of output terminals of the rectifier to trickle charge a power storage device.
