In this video, we will explore the AC current source circuit built with 2 opamps and simulated with KiCAD 6.0.
Repository with the project sources:
gitlab.com/Plinsboorg/ac_curr...
The KiCAD simulator is not perfect. It's missing a lot of features compared to LTSpice. The current list of issues can be found here:
gitlab.com/kicad/code/kicad/-...
Thanks to contributors like Evan Shultz the simulator is getting better.
Free Software. As in freedom.

Excellent tutorial! Thanks for posting it!

The component selector has an option at the bottom to create multiple instances or a component until you press escape. Or you can use COPY & PASTE. When you are drawing the schematic, instead of pressing A to add a component, you can press P, to select a power component, such as +5V, -5V, GND, Pwr_Flag.

This is crazy... I've been trying to simulate this exact circuit in easyEDA the whole day to day without any luck... Been trying to find some examples of simulating it. Now I've given up on easyEDA and was just looking for a tutorial on how to simulate in KiCAD. And here it is, the exakt circuit I've been battling ALL day! 😅 Trying to find out what effect on the output current a mismatch in resistor values have. So if anyone happens to read this and knows of a good source presenting the mathematics I would be very happy!

nice job, but i want more :) would you recommend any tutorials for simulation in KiCad 6?

Most of the interesting information is hidden in KiCAD & ngspice forums and Ngspice documentation. I don't know any deep-enough tutorials. I have one topic that I would like to learn. It's how to use generic components in KiCAD simulation. Like generic MOSFETS and OPams etc. I know that this is possible, but very few people are interested in this topic. Therefore it's difficult to find the information. Could you maybe contact me on Telegram? t.me/Plinsboorg. I would love to figure it out together if you're interested too.

Great, did this kick off? I am very interested too!

Wow, a most interesting spice video. I would like to simulate the Vishay IL300 linear optocoupler with an input and output op amp. Thank you.

sorry for the stupid question, I don't understand what's being probed? Are you saying there's positive voltage on R6, but the current is going across it the other way? Isn't that a violation of Ohm's law?

Please, post the timestamp that you're asking about. Generally I belive this SPICE simulator might have positive direction for the current in the given resistor. So with the same current, if you flip the resistor, you will read inverse value. Don't worry, Ohm's law holds true.
