An Efficient Linearization Scheme for a Digital Polar EDGE Transmitter

A new linearization scheme is proposed, which compensates for nonlinear distortions experienced in the amplitude-modulation path of a digital polar EDGE transmitter integrated in a 65-nm CMOS transceiver system-on-chip (SoC) based on the Digital RF Processor (DRP) technology. The measured amplitude...
