An embodiment of a self-aligning resonator filter circuit includes a tunable resonator having a filter output node, an oscillator having an oscillator output node, a resistance element connected between the oscillator output node and the filter output node when the self-aligning resonator filter circuit is in a tuning mode, and a phase detector loop controller coupled between the oscillator output node and the filter output node. The phase detector loop controller is configured to measure a phase difference across the resistance element, and to adjust the tunable resonator in response to the phase difference.
