Re: YouSpice
I have gone to Youspice from time to time, but it is rather less useful than one might like.? The pop-up ads and on-screen ads are rather annoying.? If I remember correctly, many of the resources

Re: Model for a Type D Flip Flop
Hi, thanks for the responses. By real model I mean not the one that came with LTspice "dflop" or a model with parameters of a real component. In other words "Real ~ More accurate".

YouSpice
I came across this site for sharing LTSpice models: https://youspice.com It seems pretty dated but has a model I'd like to look at,? but I wasn't able to get the registration process to

Re: Batch Issues
Hello All, Andy, yes you are correct, I went through half-a-dozen TL431 models and dozens of trials of other models to keep LTspice from timestep and singular matrix failures. I tried every locatable

Re: Batch Issues
eewiz, I suspect that some of your original SPICE models have changed, since the time you first ran those simulations. e.g., your TL431.mod now has only numeric pin numbers internally.? But your

Re: step recovery diode in LTspice
Look, you can't hope to "design" a circuit like this by copying an unlabelled schematic and guessing what the values of the circuit might be. In any event, you have copied it wrong. In the photo, the

Re: Model for a Type D Flip Flop
I guess you didn't find SN74LVC74A PSpice Transient Model (Rev. A) <https://www.ti.com/lit/zip/scam062> on the TI website? There are also a number of models for various types of '74 flip-flop in the

Re: step recovery diode in LTspice
Thank you so much for this, Andy! Do you have any idea how should I connect the DC bias? Clearly my way is wrong. Would appreciate the help. Thanks.

Re: Virtual ground issue in LTspice
Yes. I don't see it like that. There is galvanic continuity for every node in the circuit. That's not what I see.

Re: Virtual ground issue in LTspice
Hi Andy, No, in theory it makes no technical difference whether you ground Vref or Vn. After all, voltage is relative, so 0V/12V/24V and -12V/0V/+12V should be identical. My only reason for doing it
