  • Publication number: 20060255997
    Abstract: A differential analog filter includes a differential input that includes a first input node and a second input node and a differential output that includes a first output node and a second output node. A fully differential amplifier includes a non-inverting input node and an inverting input node coupled to the differential input. The fully differential amplifier includes a non-inverting output node and an inverting output node coupled to the differential output. A first feedback network is coupled between the non-inverting output node and the inverting input node of the fully differential amplifier. A second feedback network is coupled between the inverting output node and the non-inverting input node of the fully differential amplifier.
