Abstract
Disclosed is a voltage-controlled linearization circuit, which is mainly featured in the disposition of a resistance unit with adjustable voltage between the output end of a bias voltage circuit and a power amplifier, wherein the characteristic with voltage-controlled linear resistance is provided by receiving a adjustable voltage. Therefore, it can be used to regulate the linearity of the power amplifier, and fewer quantities of components and less area are used. The said invention is very applicable to a design requirement of communication integrated circuit of an RF power amplifier.
