%A Vo, Tuan Minh %D 2020 %T A Novel Parallel DTC Segmentation Scheme for Fractional-N Digital PLLs %K %X In this paper, we propose a new parallel segmentation scheme for the digital/time converter (DTC) which is employed in fractional- N digital phase-locked loops (PLLs) to cancel out the quantization error induced by the digital DS modulator. The proposed parallel scheme removes one redundant least-mean square (LMS) gain in compared with the conventional parallel one. Therefore, the design of the system becomes less complicated while guaranteeing a fast convergence speed of the LMS gains and a short DTC time range. The effectiveness of the proposed segmentation scheme is demonstrated via simulations of a digital PLL built at behavioral level and compared to the conventional segmentation schemes. %U http://ict.jst.udn.vn/index.php/jst/article/view/99 %J Journal of Science and Technology: Issue on Information and Communications Technology %0 Journal Article %R 10.31130/ict-ud.2020.99 %P 1-7%V 18 %N 4.2 %@ 1859-1531 %8 2020-04-30
