Abstract
According to one embodiment of the invention, an amplifier includes a gate bias circuit operable to generate a gate bias voltage and a common gate amplifier that includes a transistor having a gate biased by an output of the gate bias circuit and also having a source connected to an inductor for providing a path to ground for direct current flowing through the transistor. According to another embodiment of the invention, a method for amplifying a signal by an amplifier includes generating a gate bias voltage indicative of a difference between a reference voltage and an output voltage of the amplifier, biasing the gate of the common-gate amplifier with the gate bias voltage, and blocking, by a passive device, alternating current signals from flowing from the source of the transistor to ground.
