Amplifier Having Orthogonal Tuning Elements

Abstract

An amplifier having orthogonal tuning elements is provided. In one embodiment, an amplifier comprises an input amplifier stage having a first tuning element used to control a first performance criteria of the amplifier; an output amplifier stage operatively coupled to the first amplifier stage; a bias circuit operatively coupled to the second amplifier stage and having a second tuning element used to control a second performance criteria of the amplifier; and wherein the first tuning element operates substantially independent of the second tuning element.
