dc.description.abstract Systems and methods for providing a self-mixing adaptive bias circuit that may include a mixer, low-pass filter or a phase shifter, and a bias feeding block. The self-mixing adaptive bias circuit may generate an adaptive bias signal depending on input signal power level. As the input power level goes up, the adaptive bias circuit increases the bias voltage or bias current such that the amplifier will save current consumption at low power operation levels and obtain better linearity at high power operation levels compared to conventional biasing techniques. Moreover, the adaptive bias output signal can be used to cancel the third-order intermodulation terms (IM3) to further enhance the linearity as a secondary effect.
