WebbIn this first part of the Modeling PLLs series, learn how to use Mixed-Signal Blockset™ to model and simulate phased-locked loop (PLL) behavior. Explore integer-N charge-pump PLL simulation in depth. The focus is on rapid what-if analysis using behavioral models. Start with a blank sheet of paper in Simulink® and quickly instantiate a PLL ... WebbAbstract: This brief presents a feedforward phase noise cancellation technique to reduce phase noise of the output clock signal of a phase-locked loop (PLL). It uses a sub-sampling phase detector to measure the phase noise and a variable time delay for cancellation. Both phase noise and spurs are reduced.
