Title: EldoRF analysis on divider Post by neoflash on Dec 26th, 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 |
Title: Re: EldoRF analysis on divider Post by vborich on Dec 26th, 2005, 2:44pm 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. |
Title: Re: EldoRF analysis on divider Post by neoflash on Dec 27th, 2005, 12:38am then, how it calculate the phase noise? On which trigger voltage? |
