Patent ID: 8576009

Claim:
A method of forming a power amplifier, the method comprising: constructing one or more strings of amplification stages on a substrate, wherein constructing each string of the one or more strings includes: constructing a plurality of amplification stages, wherein constructing each amplification stage of the plurality of amplification stages comprises: constructing a semiconductor device on the substrate; placing an inductor at a drain of the semiconductor device; and placing an inductor at a gate of the semiconductor device; and coupling the plurality of amplification stages together serially to form the string; wherein the inductor at the drain of the semiconductor device of each stage in the string has an inductance that is decreased compared to the inductor at the drain of the semiconductor device of a previous amplification stage in the string; and wherein the inductor at the gate of the semiconductor device of each stage in the string has an inductance that is increased compared to the inductor at the gate of the semiconductor device of a previous amplification stage in the string.
