摘要：
A driver circuit for driving a resonance circuit is disclosed. The driver circuit includes an input to receive an input signal, an amplifier to amplify the input signal, a pulse generator to generate a pulse train based on a modulation signal, a switch coupled to the pulse generator, a capacitor coupled to the switch in parallel such that when the switch is on, the capacitor is bypassed and a Resistor-Inductor-Capacitor (RLC) tank circuit coupled to the switch and the capacitor such that the capacitor is connected in series to capacitance of the RLC tank circuit.
