Abstract
Systems and methods may include an amplifier having at least a first input port, where the amplifier includes a first capacitance associated with the first input port; a first bias circuit, where the first bias circuit comprises a series connection of a first charging circuit and a first discharging circuit, wherein a first node between the first charging circuit and the first discharging circuit is connected to the first input port, wherein responsive to an RF input signal having at least a first predetermined level being received at the first input port, the first charging circuit charges the first capacitance associated with the first input port during a first portion of a cycle of the RF input signal, and discharges the first capacitance associated with the first input port during a second portion of the cycle, thereby controlling a DC bias voltage level available at the first input port.
