Good behavioral model simulation: key to predicting first-order PLL synthesizer performance (Part 1 of 2)

In this article, the phase noise of a closed-loop, phase-locked loop (PLL) synthesizer is simulated using Agilent RF Design Environment (RFDE) and Advanced Design System (ADS) tools. The critical ...

How to Design Very Wide Loop BW High-Performance PLL Frequency Synthesizers (Part 3)

A special technique produces very wide loop BWs in high-frequency PLLs (and hence, indirect (PLL) synthesizers), thereby achieving very low phase noise rivaling that of direct (MMD) synthesizers. A ...
