Title: EldoRF analysis on divider
Post by neoflash on Dec 26^th, 2005, 5:14am

I'm using EldoRF on frequency divider or large signal amplifier.

The purpose is to estimate the amplifier or divider's contribution to periodic clock phase noise.

Simulation results are easily generated. However, i am wondering its accuracy. I never give the trigger point voltage to EldoRF, in which way it calculate period?

thanks,
Neoflash

It doesn't calculate the period unless it simulates an oscillator. For non-oscillators, it knows the period from the analysis frequency in the HB analysis card.

then, how it calculate the phase noise?
On which trigger voltage?
