Hello All, I'm trying to do transient parametric sweeps (e.g. VCO frequencies for different input voltqges) in ngspice, but it has been hard to find good examples. Did anyone here do such type of simulations, who can send me a nice examples and good references (apart from ngspice manual, of course)? thx in adavce :)

Some repositories by @User and his students show a good example of how it is done.

great, I'll take a look, thanks @User!

Oh I think it was parametric DC analysis, Sorry I must have missed that

I want to sweep in steps the input voltage of the VCO, and capture for each input value the waveform, and then measure the frequency to obtain the VCO gain, linearty, etc. From what I read, I think it's different for transient, you don't have the option of declaring sweep parameters on the statement... that's why I was asking if there were some examples around, but it seems it's rare to do parameter sweeps for transient simulations

thanks for the references, it's more clear now 🙂
