Re: the totoal current of the VCO doesn't convergence !!! wh
==========================================
Thx for your advice. I change the maxstep and simulation algorithm
It seems convergence but still oscillating.perhaps it's the VCO's pull and push current
ebookee
When I doing the tran simulation(Using Spectre) I foud that the current of my VCO doesn't convergence !!! why?
anybody met this statues before.
Hi all,
i want to know how to analyse this cross-couple delay cell's delay time for a ring oscillator.I want to find out its delay time in order to decision the VCO frequency , but I don’t know how to do the small signal analyse? If T ~ Rout*Ctot , how to find out Rout? It is a cross-couple...
