Abstract
A system includes a tunable bulk acoustic wave (BAW) resonator device and a direct-current (DC) tuning controller coupled to the tunable BAW resonator device. The system also includes an oscillator circuit coupled to the tunable BAW resonator device. The DC tuning controller selectively adjusts a DC tuning signal applied to the tunable BAW resonator device to adjust a signal frequency generated by the oscillator circuit.
