Abstract
Disclosed are apparatuses and methods to overcome technology limitations to achieve linearity and efficiency performance suitable for practical wireless communications systems. In an embodiment, an amplifier is provided that superimposes the transconductance from a common source amplifier with inductor degeneration with the transconductance from a common source amplifier without degeneration. In an embodiment, an amplifier is provided having a feedback-balun-transformer that provides electro-magnetic coupling between primary, secondary, and negative feedback degeneration inductors and a differential to single-ended conversion output.
