A novel digital PLL with good performance and very small area


A novel digital PLL(Phase Locked Loop) is presented in this paper. It uses three types of digital delay control methods, including delay cell number adjust, delay cell load adjust and cycle control to digitally control the DCO(Digitally Controlled Oscillator) output clock frequency, so as to get wider frequency range and smaller jitter. This PLL uses NAND… (More)
