System and method for controlling resonance frequency of film bulk acoustic resonator devices
Disclosed is a system and method for controlling a resonance frequency of a Film Bulk Acoustic Resonator (FBAR) device. The system includes at least one switching capacitor coupled to the FBAR device and a modulator. The at least one switching capacitor includes at least one capacitor and a switch configuration disposed in series with the FBAR device and the at least one capacitor, which is switch configuration capable of opening and closing connection of the at least one capacitor with the FBAR device. The modulator is coupled to the switch configuration, which generates a switching condition signal based on the manufacturing variation in the FBAR device and the environmental effects on the FBAR device. The switch configuration performs opening and closing of the connection of the at least one capacitor and the FBAR device based on the switching condition signal.
