Abstract
Certain embodiments of the present invention provide a loosely-coupled oscillator including a circuit and an electronic device that are not physically connected. The electronic device may include an amplifier for amplifying a signal to produce an output signal and include a wire connected to an input of the amplifier. The wire can be electromagnetically coupled to the circuit that is physically disconnected from the electronic device. The output signal can be produced at an output of the amplifier without transmitting an excitation signal from the electronic device to the circuit and when the wire is electromagnetically coupled to the circuit.
