Abstract
Provided herein is a digitally controlled segmented RF power transmitter with a digital processing part and an RF power amplification part having a plurality of segments. The digital processing part has a clock generation block arranged to generate n equi-phased clock signals with a 50% duty-cycle (f, C), and a sign-bit phase mapper unit arranged to receive the n equi-phased clock signals (f; C), and sign bits (Sign, Sign), and to output a set of m, m≤n, phase mapped clock signals with a 50% duty-cycle (CLK; C) using a predetermined phase swapping scheme. Each of the plurality of segments includes logic circuitry receiving the set of m phase-mapped clock signals with a 50% duty-cycle (CLK; C), and arranged to provide the respective segment driving signal with a duty-cycle z of less than 50%.
