An integrated resonator apparatus comprises a piezoelectric resonator, an acoustic Bragg reflector coupled to the piezoelectric resonator, and a substrate on which the acoustic Bragg reflector is disposed. The apparatus also includes an active heater layer covering the piezoelectric resonator. Heat produced by the active heater layer is controllable by an amount of current provided through the heater layer.
