Re: MosFet "LEVELS" in LTSpice compared to other spice simulators
Hello, No. Most of the parameters are the same, but especially HSPICE has often additional parameters. I vaguely remember that Spice programs can have different equations to calculate Weff and Leff,

Re: Plot Log curve as inverse to Antilog (Exp) curve?
Hello, I don't understand your log-plot. May be you simple asked for the step response of RC-circuits. .param tau = 0.2 V = 5*(1-exp(-time/tau)) Best regards, Helmut

Plot Log curve as inverse to Antilog (Exp) curve?
I've uploaded 2 files to the Temp folder: curve_exp.jpg curve_log.jpg To get the exp curve in curve_exp.jpg I used: Value: V=5*exp(7*(time-1)) in a Behavourial Voltage source. It gives an exponential

Lock horizontal axis
(1) Choose any plot, drag a rectangle over it all, then all plots get same time axis limits. (2) Doing this with "Manual Limits" only zooms the plot selected (not all). So: What I'd like to be able to

Re: Pull-Push transformer for valve amp in LTspice
Hello analogspiceman I'm not denying that your library works (I have used it a few times, successfully) or that a quasi-real transformer can not be built around the Chan core, but I have never used it

Re: Pull-Push transformer for valve amp in LTspice
Hello Vlad, a transformer has multiple windings, but only one core (which is the only nonlinear part). That is why LTspice does not allow coupling between saturating inductors (either Chan or
