Abstract: A cancellation circuit to remove the anti-resonance signal from a resonator. Micro-mechanical and surface and bulk acoustic wave resonators include an anti-resonance in an output signal. This has an undesirable effect on certain types of systems in their function and performance. An anti-resonance cancellation circuit removes the anti-resonance from the output of the resonators by providing a signal which is subtracted from the output of the resonator. The cancellation circuit includes a capacitor which is matched to the static capacitance of the resonator. The loads of the resonator and cancellation network are also matched.
