摘要： A film bulk acoustic resonator filter may be formed with a plurality of interconnected series and shunt film bulk acoustic resonators formed on the same membrane. Each of the film bulk acoustic resonators may be formed from a common lower conductive layer which is defined to form the bottom electrode of each film bulk acoustic resonator. A common top conductive layer may be defined to form each top electrode of each film bulk acoustic resonator. A common piezoelectric film layer, that may or may not be patterned, forms a continuous or discontinuous film.

摘要： A film bulk acoustic resonator (FBAR) comprises a piezoelectric film sandwiched between a top electrode and a bottom electrode. A temperature sensor is provided to sense a temperature to determine a temperature induced frequency drift for the FBAR. A voltage controller operatively connected to the temperature sensor supplies a direct current (DC) bias voltage to the FBAR to induce an opposite voltage induced frequency drift to compensate for the temperature induced frequency drift.
