If you want to generate one curve for a temperature range, you can in the "Edit simulation Command" choose the "DC sweep" tab instead of the "Transient" tab. There you only need to write "temp" in the "Name of 1st Source to Sweep" and set the start, stop and increment values (in °C). When you simulate the circuit you get one curve representing the whole chosen range.

You're amazing dude

As always Dave, great piece of work. Your forum is always a platform to learn new things. Thanks for the input

You can not get enough thumbs up for this one. Thank for your great way of teaching. And inspiring attitude. And humor. And much more.

Love it. Thanks for the tutorial! We learned off a 20+ year old iteration of Pspice at uni. Worked well but the app code was really starting to show its age. Glad to see some companies are still giving circuit sim some TLC!

Great tutorial Dave, I have used LTspice before (nothing complicated), but never imagined that it has temp sweep.

Brilliant idea, sweeping through resistor values and seeing what effect it has on circuit response.

I wish I had a bigger thumb to give.. Learned about temp sweep. Didn't know it existed. It pays to watch Dave's videos.

Thanks for this. I learned something useful. Didn't know I could step params.. I was looking for a variable pot or switch like the old electronics workbench, but this .step thing can be used to achieve similar results. Thank you.

Hi Dave thank you for that video. Greetings from the beautiful Greece

Great video Dave, and just in time. I was looking for a good simulator to do a high Q band-pass filter analysis, i had looked at LTSpice. But it seam unfriendly at first look, now i will give it another try. These small tutorials are great.

excellent tutorial. Thanks for spreading the word!

Thanks for sharing this, I learn something useful about parameters sweep

Excellent tutorial!

I must agree with you Dave, I love LTSpice, not only is it free but it is accurate and easy to use, compared to others like CircuitLab and EveryCircuit, neither of which are free, and neither are full-blown SPICE simulators. Not only that but you can add in various manufacturer's component databases, which is very handy for simulating circuits without Linear Tech's own devices. 10/10 IMO

thanks a lot! do you know how to make a graph of voltage over temperature

Thanks Dave, great tutorial!

You would need a positive tempco device at 0.6V to offset the negative 0.6V tempco of the transistor (or equivalent)

I really liked this one. Good job.

Very good tutorial - do more on LTspice please! One correction: at 15.10 to 15.25 its the other way round with temperature and voltage i guess :-)

thank you for the great tutorial it would be great if u could help me with the following question: how can i simulate a detector (sensor "resistance" that change it's value over temperature)?? that mean's the resistance should change with different temperature thank you very much

How can I identify in the graph which trace correspond to which parameter value?

Thanks so much. Had no Idea the sweep command existed.

Sounds like a good series! :D

Thanks so much. That was awesome!

Thanks Dave, 8 years later!...

I wonder is it possible to easily improve 2T constant current source for better stability?

Hi Dave, very good tutorial. What about Monte Carlo analysis on LTspice?

The temp varied for the entire ckt, but obviously every component is not going to have the same effect on the ckt; some parts will have little effect on the output and some will have a large effect. When the output varies with temp more than you want, how can you find out which part(s) is the villan? Wouldn't it be neat if they applied color to the schematic, showing which parts had the most effect (sort of like an IR photo)?

Have you ever usd Tinapro? Iv been using it for years and there are more options and functions then i could ever need but theres so much going on its not easy to get used to

Damn, yes, I forgot to include this one.

Nice vid, i could of used this about 2 months ago while designing my electronics school projects.

Thanks for sharing!

What other circuit drawing type software is there?

I would like to see an Astable Multivibrator circuit simulated, something never saw on KZread due to the no variability of components in a simulated environment with the consequent fail in the simulation of such circuit!

Excellent!!

Dave! I love ya haha. I have been using ltspice for about a week and now I know it's your favorite and you have shown some nice thermal sturf with it, wooot! Would you recommend freeware that is as good as ltspice to make use of the netlist for vero/strip/bread boards (verocad was useless, veecad imports a list but doesn't make sence of it). freeware pcb software would be cool too. Whats your recomended freeware pack. Your an inspiration and a top geezer.

I've known how to do this only because my school's IEEE invited some reps from LT to present some concepts in LT spice to us.

50 videos is too much, but it would be nice to continue pointing out useful bits like this.

I would like more on LTSpice.

Bandgaps.asc is good example of temp effect on electronics.

Adding some heat to the circuit with some LTspice? :D

It would need 50 videos I suspect!

U make LT so easy and it really isn't that complex of a program

Are there any other hidden gems?

"Something magical like that", haha funny!

You try to give the video more brightness it will be great if you do

If you know there's only one "bias point," Instead of doing a transient sweep to get node voltage (as you are doing in this case), you cat do an operating point calculation.

how to plot voltage versus temperature?? am having trouble doing that.

write .step temp initialtemp finaltemp stepvalue and in simulation cmnd-> dc sweep-> .dc temp initial final step

based on previous comment (5 years ago) just insert temp as source name in DC analysis and insert start and stop temp and also step size. just as simple as that

This works pretty good, thank you!

Can you make an LTSpice tutorial? All the other ones suck.

nice!

Can we use temperature without sweep??? i.e. single temperature value. If so....then how???

Music Lovers maybe you can write , .step temp 50 50 0 or something like that.

If you want to change a single global temp, make a Spice Directive with the '.temp' parameter, no step needed. Example: ".temp 50" is going to give me a global temp of 50 degrees.

I know this is old but if you haven't gotten an answer yet... monte carlo is also available - "mc(val, tol)" command.

No you can't, as with any spice program. Some simulators might include some form micro simulation, but you are better off using the vendor tools.

Bob was right !

Yes, it's a real shame that it's not obvious.

the temp won't be in C - it's kelvin, I believe...

I take it back. LTSpice does it in C. Pretty sure Berkley spice is in K
