CN1074 ADIsimPLL

Dear SIr/Madam

 

Recently I saw reference circuit CN0174 "Low-noise 12 GHz microwave fractional-N phase-locked PLL using active loop filter and RF prescaler",  reading its 12 GHz PLL's measurement performance versus simulated phase noise performance Figure. I do not know how to set simulation parameters to obtain at 12GHz output when the phase noise reaches -130dBc / Hz @ 1kHz. The ADIsimPLL simulation design file link in the document has been invalidated.

I wonder how to simulate to implement the above performance.

 

Thanks.
