Abstract
In one embodiment, a method includes receiving a radio frequency (RF) at an antenna; generating negative feedback to linearize an amplifier by resistively or transformer coupling an output signal of a transistor of the amplifier to the input of the transistor; generating a rectified voltage by rectification of the output signal of the transistor; generating a constant reference voltage; and outputting a control voltage or a control current to the transistor based on the sum of the reference voltage and a first voltage derived from the rectified voltage. The output of the control voltage or control current facilitates control of an operating point of the transistor.
