Phase Noise: Under the Hood | Modeling PLLs Using Mixed-Signal Blockset

 This is the sixth video in the Modeling PLLs Using Mixed Signal Blockset™ series and it takes a deeper dive into phase-noise modeling. Go under the hood of the Ring Oscillator VCO block to see how flicker noise is efficiently generated using a low-order IIR filter. Go inside the Phase Noise Measurement block to see how zero-crossing information is captured and postprocessed using MATLAB® callbacks. In the process, you’ll also learn about the inner workings of Simulink® masks and how MATLAB and Simulink are tightly integrated.
