EldoRF analysis on divider
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,
