Abstract
A power amplifier with analog predistortion is disclosed. In one aspect, a signal in the transmission chain is sampled to determine if a phase distortion (delay or advancement) is present. Information about the sampled signal is provided to a control circuit, which uses an analog predistortion circuit to inject a correction signal into the transmission chain so as to offset or compensate for the phase distortion. In an exemplary aspect, the analog predistortion circuit may use a variable capacitor to generate the correction signal that is injected. This detection and adjustment may be done in the front end of the transmission chain so as to avoid reliance on a baseband processor. Use of such analog predistortion helps maintain desired linear operation over the large bandwidths of emerging wireless communication standards.
