Re: Pull-Push transformer for valve amp in LTspice
What's the equality between the ratios of the inductances and the number of turns? Vlad ______________________ ltspicegoodies.ltwiki.org -- holding, among others: a universal analog/digital filter,

Re: Pull-Push transformer for valve amp in LTspice
Thank you so much!!! Things are starting to become much clearer now. If you don't mind, may I ask, why did you take a quarter of the total primary inductance? Why not just half it?

Re: Lock horizontal axis
Hi Helmut, It's actually the X-axis I have trouble with - see "X-Axis different scales.jpg" in Temp. Regards Stephen. PS Mike told me (quote) "lock horizontal axis should do that."

Quite a mess, as expected :) Thank you Andy, I think I have it clear now.

Simulating a TI DRV103 with LTspice?
I was looking for an electronic "dash pot" for a solenoid and found the TI DRV10{2, 3} series of delayed-start PWM devices.? Downloaded TI's DRV103 spice file, looked, did a few sort-of educated

I also tried .meas ampx MAX V(Out_1) I(V1) thinking I can plot the max of V(Out_1) vs. I(V1) I tried to do it by adding another directive .meas ampx MIN I(V1) for no avail. Any suggestions is most

Helmut Is there a way to optimize on 2 or 3 variables and plot results like you did? i.e. Ton Tperiod R of the inductor for example? Thank you LTspice@...> wrote:

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

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

(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
