A filter includes, in at least one aspect, one or more differential inputs to receive one or more differential input signals, a first filter stage to provide one or more primary poles corresponding to a first frequency associated with the one or more differential input signals, a second filter stage coupled with the first filter stage to provide one or more secondary poles corresponding to a second frequency associated with the one or more differential input signals, the second frequency and the first frequency having a predefined relationship, and one or more differential outputs coupled with the second filter stage to provide one or more differential output signals. |
