Beschreibung
Zusammenfassung:	A circuit includes: a first resonator; a temperature compensation circuit including a resonator group-delay analyzer and a second resonator; oscillator control circuitry; and a controller. The resonator group-delay analyzer is configured to determine a group-delay parameter responsive to operations of the second resonator. The controller is configured to provide a control signal responsive to the group-delay parameter. The oscillator control circuitry is configured to adjust a frequency of an output signal of the oscillator control circuitry responsive to the control signal.
