Mar 4, 2014 · I need to add a new Diode to LTSpice to perform some academic simulations but i don't know how to do it. Adding just a Spice Directive looks like it's not enough...

Jul 26, 2022 · I modified the LTspice models I have for SPDT and DPDT relays to make their coil operation non-polarized (typical of most standard mechanical relays), and added hysteresis to their energized coil voltage (≈74% of rated voltage), and de-energized coil voltage (≈25% of rated voltage). As before...

Dec 11, 2024 · I tried to simulation this op amp circuit in LTspice, but I dont really understand the pin V+ and V- of op amp, are these pins must be connected to an external dc source and the dc source value is optional, right?. And what is the function of V+ and V- …

Jun 7, 2021 · Hi everyone, I have been looking for some tutorial or book where I can find information how to create my own LTSpice model. I would like to understand what symbol in the model mean. For example, there is below code for BAT64 diode: * Infineon Technologies Discrete & RF Semiconductors...

May 9, 2024 · Is it possible to simulate microcontroller or arduino on ltspice. If not, then is there a way to do so in ltspice .

Nov 16, 2020 · Hi guys! I need to model a RCL circuit with two switching that are closing at different time. How can I do it? I tried computing initial conditions but is very time consuming. Is there another way to model them? May a use one of the available switches in the library? Thanks!

Feb 13, 2010 · How do I specify the initial charge voltage of C4 like that of C3? Right clicks on C3 & C4 both popup the same menu with options like capacitance values and Rser(ESR). On C3, the change I made to Rser is seen on the schematic but on C4 the Rser value I entered don't even show up on the...

Mar 9, 2025 · I'm seeing a problem with my project on LTSpice. The PMOS circuit is powered by 14VDC and is using a 2n3904 to switch the Gate on the PMOS. The gate is going from 14v to 0 v, but the Drain is only going from 13.98v to 13.38v. Can someone tell me why this is happening?

Nov 27, 2024 · Old troglodyte that I am, I'm still using LTspice IV since I prefer it's interface and I know it's hot key designations. And one big annoyance to me is that 24 doesn't remember my settings when I switch between AC analysis and Transient analysis, whereas IV does. I often frequently switch between an AC Bode plot and transient step response when I'm checking the …

Jul 27, 2020 · Hi Sam, Find the standard.bjt folder in your LTSpice, I use Microsoft Explorer to display the files This is my Path to the folder, Yours should be the same. Use a text editor to open standard.bjt file, you should see the list of all the transistors you have available. Paste the the transistor model text into that folder. Ask if you have problem ...
