Abstract :
In this paper PLL Design tool, created in Matlab from MathWorks, has been presented. The tool allows to analyze loop stability and phase noise of PLL, based on phase-locked loop linear model. Fast evaluation of loop filter components values for popular passive and active filters is possible. The created tool allows to analyze PLL parameters, like loop filter components values, VCO gain and charge pump current variations impact on loop stability and phase-noise. Algorithm for phase-noise calculation, based on transient PLL simulation, has also been implemented. Thanks to these features the created tool is a valuable aid for PLL designer on all design steps.
