Abstract: A circuit and method for filtering a signal. An amplifier receives an input signal and generates a differential output signal. A first resonator having series and parallel resonant frequencies is connected to the positive output port of the amplifier. A second resonator having series and parallel resonant frequencies is connected to the negative output port of the amplifier. The first and second resonators are coupled at a connection point. A buffering device receives the combined outputs of the resonators and outputs a filtered signal. The filtering method receives signals and passes them through the elements of the filter circuit to generate a filtered output signal.

Abstract: A circuit and method for filtering a signal. An amplifier (330) receives an input signal (310) and generates a differential output signal. A first resonator (340) having series and parallel resonant frequencies is connected to the positive output port (335) of the amplifier. A second resonator (350) having series and parallel resonant frequencies is connected to the negative output port (336) of the amplifier. The first and second resonators are coupled at a connection point (340). A buffering device (370) receives the combined outputs of the resonators and outputs a filtered signal. The filtering method receives signals and passes them through the elements of the filter circuit to generate a filtered output signal.
