ABSTRACT:
A dynamic biasing system (“DBS”) for dynamically biasing an amplifier with an adjusted bias signal is shown. The DBS may include a first biasing circuit that produces a bias signal and a second biasing circuit in signal communication with both the first biasing circuit and the amplifier, wherein the second biasing circuit compares the bias signal to a predetermined threshold and in response produces the adjusted bias signal.
