Abstract
A method, packaged semiconductor device, and system for controlling a secondary amplifier output current based on an input signal received from an amplifier input, converting electrical energy to magnetic energy at a secondary amplifier output inductor, coupling the magnetic energy from the secondary amplifier output inductor to a primary amplifier output inductor, converting the coupled magnetic energy to induced electrical energy at the primary amplifier output inductor, combining the induced electrical energy with output electrical energy from a primary amplifier gain element, and applying a combined electrical energy including the output electrical energy and the induced electrical energy to a primary amplifier load are provided.
