摘要：
A circuit (102,110) may be tuned to resonate at a driving frequency. The circuit includes a source (110) that provides an output at a drive frequency and a resonant circuit (102) having an input coupled to the source, an output, and first and second selectable resonant frequencies. The first resonant frequency is below the drive frequency and the second resonant frequency is above the drive frequency. A control (112) coupled to the resonant circuit output selects the first and second resonant frequencies to cause the resonant circuit to provide an output at an apparent resonant frequency equal to the drive frequency.
