Abstract
A Q-controlled microresonator and devices including such resonators.
Claims1
A method for passband correction of a filter having a controlled quality factor, comprising:
- providing at least one Q-controlled electromechanical resonator as at least one biquad of said filter;
- and
- adjusting a quality factor of said at least one Q-controlled electromechanical resonator to correct a passband of said filter, using negative feedback such that said controlled quality factor is independent of a value of said quality factor of said resonator.
