# Which tool is being used to create the following figure?

I am trying to determine the circuit drawing tool that is used to create figures in some papers I come across every once in a while. The tool is able to create some very slick-looking diagrams/schematics. Here is one example:

I like everything about the schematic above -- in particular, I really like the way the MOSFETs look and the ground symbol. Whenever I see schematics drawn with this tool in papers, I am always impressed with the way it looks in the paper (even if the author's interpretation of their results is not quite right).

In another similar question, xcircuit was given as a possibility, but the xcircuit drawn figures I've seen don't look anything at all like the example above.

• It is possible that they are templates in some office suite, not entirely improbable. Otherwise, no idea. Apr 21, 2018 at 15:48
• Probably draw by a person in a graphics package. I've achieved similar graphics using little more than MS Paint. Apr 21, 2018 at 15:48
• My guess is, it has been drawn in Adobe Illustrator. Although other tools with SVG capabilities could do the same.

• The error in the top circle of S2 implies that it's hand drawn.

Try Cirkuit$^1$ together with Circuit Macros if you're into LaTex.
$^1$ Reminds me of a Power Systems professor (I think he was from Romania) I had back in University, who would pronounce "circuit" as sare-kweet.
