Abstract:
A drive circuit for a resonant system provides an excitation signal having an amplitude and a phase. The resonant system provides a feedback signal representing an oscillation amplitude. The amplitude of the excitation signal is reduced for a substantially constant feedback signal amplitude by modifying the excitation signal phase.
