Abstract
A nested multi-stage polyphase filter can comprise: a first filter stage and a second filter stage. The first filter stage can be connected to the second filter stage via first through fourth intermediate connections. The first filter stage and the second filter stage can be laid out in a nested-ring layout. The first through fourth intermediate connections can be laid out so as to not cross over each other.
