Abstract
Systems and methods which implement degeneration circuitry in a single-ended amplifier circuit to mitigate distortion associated with one or more amplifier components are disclosed. A degeneration circuit of embodiments adds an impedance to cancel the second-order distortion of an amplifier transistor of a single-ended amplifier circuit. A bias circuit may be provided to minimize bias offset between an amplifier transistor and a corresponding degeneration transistor.
