Hi everyone, I want to add a d flip flop(data type flip flop) in my model. Unfortunately, the dflop which I'm using has no online spice model. I want to ask if I can use the default dflop symbol( avai

Hi, : I even don't know what's the best topic name to name it. It's I have a .AC sweep ,which I tried to get transfer function in 's' expression with SAPWin. But I can't get right output, I don't know

Is it possible to set up a circuit simulation such that multiple temperature zones controlled by a variable are in force. Say measuring a current or voltage in one part of circuit operating under one

I am trying to understand a pnp differential amplifier circuit (photos here) as I'm trying to fix a piece of equipment. The simulation is giving me strange results. I would have expected to get a high

Hello Everyone, I was just curious if anyone has a dynamic Power or Voltage Slew Rate controlled source, that they could share of point me to. I need the source to act as the stand in to an external p

Why don't you post the .asc file? That would be much easier for us.

Good morning, I have seen on WIKI the library published by Helmut with name (74HC.lib). How can I independently use the different components it contains and assign them a symbol to work with them?? I

Hi I can not seem to find the spice models of the following components. Please help STGP20V60F IGBT 600V 1A, Diode, FR105G-K R0G diode IDP15E65 diode TC4422AVPA MOSFET driver Opto isolator 4N25

Thanks Andy for the fast reply. but where can I see that im relativly new to working with LTSpice

I uploaded Rectifier_Test6.asc to the TEMP folder just now. It is a full bridge rectifier being driven by a sinusoid with a series resonant tank. I'm confused why the maximum time step is having such

I found 20191121_FIR_BFP_hilbert+HT.zip while scanning for a working example of a Hilbert transformer in the file area of this group. The simulation uses a FIR subcircuit from Vlad's http://ltspicegoo

I am searching for spice models of these elements : PDB-C139,PGM 5516,BP103.Thank you in advance!

I have installed LTspice 17.0.42 in a Macbook Air running MacOS 11.6.4 (BigSur) I also have several asc files that were generated with a previous LTspice version on a previous MacOS (Mojave), all thes

Hi i wanted help regarding the voltage controlled switch. I modelled a voltage controlled switch according to the following youtube video: https://www.youtube.com/watch?v=PWRmUsqW0DE Now it works when

Hi, ; One thing that confused. in the file section, 'UCC25600Test.zip' provided in 2016 year, it runs ok in LTspice IV Version 4.231, but fail in LTspice XVII. It shows up the msgbox 'u1:x2:v1: requir

Dear All, I want to simulate a LCC-Half Bridge Converter. The circuit is using a resonant tank which needs to be calculated before simulations can take place. It’s quite common and necessary to plot t

Hello All, I have uploaded a zip file containing a simulation schematic allowing one to plot the hysteresis curves (B-H) of a Chan inductor. https://groups.io/g/LTspice/files/Temp//Hysteresis.zip (the

I'm trying to recreate the test fixture and model creation that was documented by Sid Antoch in his book, Op-Amp Circuits: Simulations and Experiments, www.zapstudio.com. I'm really just a nube to LTS
