Abstract
An analog input signal (X) is processed by a Peak to Average Ratio Reduction (PARR) block to diminish the difference between peak amplitudes and average amplitudes of the analog input signal (X). After, a distorted signal (h(n)) having low peak to average amplitude ratio, generated at the PARR block output, is processed by a delta sigma modulation (DSM) block converts the distorted signal (h(n)) into a digitally modulated distorted signal (h_dsm) with high signal to noise ratio (SNR). Afterwards, the digitally modulated distorted signal (h_dsm) is corrected and amplified by a Class-D RF power amplifier fed by a feeding signal (env) generated from a digital correction signal (z_dsm). As a result, a digitally modulated signal (y(n)) with high signal to noise ratio (SNR) of the analog input signal (X) is generated at the output of the Class-D RF power amplifier.
