Abstract
This paper presents a Volterra -series bias based circuit of Class-AB RF power amplifier.
This c i r c uit design is power and accurate for nonlinear circuits. In Class-AB RF PA design, and analyze with bias
circuit and it makes balance between efficiency and linearity , which make the application of the Volterra-series bias
ciruit is more flexible in practical applications. The measurement result verifies the effectiveness of this design and a
test die is fabricated.
