Then EPADs might be a decent approximation, some still available at Mouser/Digikey. Another option would connecting a BC547 directly to mains to make it truly, Sevres-certified junctionless, but something tells me it's not the case. Best reagds, Piotr

Kist curious .The traditional way to implement transresistance without a junction is with a triode vacuum tube. Plain old bipolar junction transistors are the high-gain winners nowadays, and MOSFETs are the high-density winners. What design win can a junctionless transistor achieve? None, that I know of. It's likely to remain a lab curiosity for a few more decades.

They have been around for over a century. https://en.wikipedia.org/wiki/Fluidics John

I did not see the value of keeping them.... regards, RS
