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 ...

SOC-PLL design requires trade-offs

PLLs (phase-locked loops) are common analogcircuits in SOCs (systems on chips). Almost allSOCs with a clock rate greater than 30 MHzuse a PLL for frequency synthesis. However, a“one-size-fits-all” PLL ...

Select The Right PLL-based Oscillator For Your Timing Application

More than 10 years ago, the frequency control industry introduced PLL-based (phase-locked loop) oscillators, an innovation that pioneered several features previously unavailable with traditional ...
