    Abstract: An aspect relates to a filter or a first gyrator including a first set of cascaded inverters, and a first set of one or more passive devices coupled to the first set of cascaded inverters. Another aspect relates to a method including applying an input signal to an input of a first one of a set of cascaded inverters coupled to a set of one or more passive devices, and receiving an output signal from the set of cascaded inverters, the output signal being a filtered version of the input signal. Still another aspect relates to a transceiver including a filter with a first set of cascaded inverters, and a first set of one or more passive devices coupled to the first set of cascaded inverters; and a mixer coupled to the filter.
