Nowadays we are trending towards multi-standard and multiband communication, for that purpose, an efficient modulation method is required to meet the demands of users. In this paper, we analyze the performance enhancement in different types of delta sigma modulator based Transmitters by improving the coding efficiency and signal to noise and distortion ratio (SNDR) using multilevel architecture. Polar...
This paper presents a novel implementation topology of three- level delta sigma modulation (DSM) schemes. The delta sigma modulation converts envelope-varying signal to pulse modulated form, which can be applied directly to high efficient switch mode power amplifiers (SMPA). Multilevel DSM is proposed over bi-level DSM to enhance coding efficiency (CE) and signal to noise and distortion ratio (SNDR)...
