Re: LTSpive IV vs XVII voltage generators
Hello Larry, I haven't discovered this behavior, because I used sine-burst only a very few times in 17 years. I just checked your reported case and indeed it's different in LTspiceXVII. It's difficult

Re: How to include component values in LTSpice trace formulas
Doug asked: "I would like to be able to define a trace for the energy stored in a capacitor using the formula E= 1/2 * V^2 * C. But I can't find how to include component values such as capacitance, C,

LTSpive IV vs XVII voltage generators
I loaded an old circuit that was created in LTSpice IV into LTSpice XVII today and noticed that the voltage acts differently. Specifying a sine wave voltage source with some number of cycles and some

Re: Edge triggered b-source logic and integrated averaging in LTspice
Hello Vlad, I noticed that bug and reported it several days ago. Perhaps it would help if you reported it as well. It only is a problem for "B I=" sources that include a defined function and that

Frequency calc durung trans sim
Hi everyone I'm working on a B device method to calculate the frequency of a square wave during a trans sim. I'm uploading a file "CalcFreqFromTonToff.zip". Its not a real accurate method but I was

How to include component values in LTSpice trace formulas
Just joined the group and don't know how to search whether this has already been addressed - guidance on that would be appreciated! But here's my question: I would like to be able to define a trace

Re: Edge triggered b-source logic and integrated averaging in LTspice
Hello analogspiceman It's a nice example on how to use idt() as idt(0, x, y), instead of the more usual idt(x,

Re: Edge triggered b-source logic and integrated averaging in LTspice
Hello analogspiceman, Thanks a lot for ths idea of a "sampled" average. I have made an example with your formulas. Please check my circuit. I wonder a little bit were the integration really starts and

Edge triggered b-source logic and integrated averaging in LTspice
Hello all, These following functions are intended to be used in b-sources. The first two replicate edge triggered logic such as is used in the a-device DFLOP clock input. The last function is more

Done! http://adrianimmler.simplesite.com/440951057 http://adrianimmler.simplesite.com/440951057 The generic triode spice model code on the "...for vacuum tubes" page is removed, so a visitors mind

Re: Problems using Pspice fet model for infineon BSR202N.
Hi richard. I made a solution to the problem of calculation, but the temperature of the transistor chips is zero, which is not correct. I do not like these models. To all, due to the complexity may be

Re: Problems using Pspice fet model for infineon BSR202N.
I think you are right. I made a mistake. Sorry. sbb2.zip in the files area should demonstrate the problem. I will have a look at the help file you have refereed to. I have looked at similar files -

Re: Problems using Pspice fet model for infineon BSR202N.
I have found and used the BSR202N model and test circuit from Tony(?) The test circuit worked - but in my circuit - I ma getting similar results to that from my original version of the infineon model.
