Abstract
Methods and apparatus for transferring a signal from a first stage of an amplification circuit to a second stage of an amplification circuit via a matching network are described. An example matching network generally includes a transformer, a first coil selectively coupled, inductively, to the transformer, and inductive path(s) coupled between a first input node and a first output node of the transformer. Each inductive path includes a respective second coil selectively coupled, inductively, to the transformer. The transformer includes: the first input node and a second input node for coupling to the first stage; the first output node and a second output node for coupling to the second stage; a primary winding coupled between the first input node and the second input node; and a secondary winding inductively coupled to the primary winding and coupled between the first output node and the second output node.
