  2. 1. Digital Phase Locked Loops for Radio Frequency Synthesis

    Author : Ahmed Mahmoud; Integrerade elektroniksystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; PLL; DPLL; VCO; DCO; loop filter; DS modulator; phase noise; spurs; quantization noise; BBPD; TDC; DTC;

    Abstract : The demands for an ever higher data rate and a more varied functionality at minimal cost and power consumption have been the driving force behind most innovations in wireless communication systems. Intensive efforts have been made to develop Radio Frequency (RF) Integrated Circuits (ICs) and systems using low-cost Complementary Metal Oxide Semiconductor (CMOS) processes. READ MORE

  4. 2. Distributed Clocking and Clock Generation in Digital CMOS SoC ASICs
