| Abstract: Apparatuses and methods for tuning center frequencies are described
herein. Examples of tuning described herein including tuning using
feedback from the resonator. Variable gain feedback for tuning of
acoustic wave resonators is provided in some examples. An example
apparatus may include a resonator and a feedback loop. The resonator may
be configured to receive a tuning signal and to provide a feedback
signal. The feedback signal may be based on the tuning signal. The
feedback loop may be configured to receive the feedback signal from the
resonator. The feedback loop further may be configured to provide the
tuning signal to actively tune a center frequency of the resonator. The
tuning signal may be based on the feedback signal. |
