Abstract
Systems and methods for providing an adaptive bias circuit that may include a differential amplifier, low-pass filter, and common source amplifier or common emitter amplifier. The adaptive bias circuit may generate an adaptive bias output signal depending on input signal power level. As the input power level goes up, the adaptive bias circuit may increase the bias voltage or bias current of the adaptive bias output signal. A power amplifier (e.g., a differential amplifier) may be biased according to the adaptive bias output signal in order to reduce current consumption at low power operation levels.
