Abstract
A circuit includes an amplifier having an input that receives an alternating current (AC) waveform and an output that is coupled to a power source via a bias resistor. A bulk acoustic wave (BAW) resonator is coupled in parallel to the bias resistor via the power source and the amplifier output. The BAW resonator and the amplifier output forms a band pass filter to filter the AC waveform received at the amplifier input and to provide a filtered AC waveform at the amplifier output.
