| Oct 31, 2018 at 13:13 | comment | added | Hearth | I know that the falstad circuit simulator has a model for a tunnel diode. It might also be possible to use a lambda diode, which is a simple configuration of two jfets that exhibits negative differential resistance. | |
| Oct 31, 2018 at 13:08 | comment | added | Bimpelrekkie | What you need is a proper model for a tunnel diode. It will be a challenge to find one I think. You could also make your own model, that's not so easy, to get an idea, read here: hindawi.com/journals/apec/2011/830182 and pdfs.semanticscholar.org/7b2a/… | |
| Oct 31, 2018 at 12:54 | comment | added | user16307 | @Andyaka here they use tunnel diode for negative resistance www-m2.ma.tum.de/bin/view/Allgemeines/SGMVDP I need the actual circuit to implement. I couldnt find a finished example with values or exact components. | |
| Oct 31, 2018 at 12:51 | comment | added | Andy aka | Most simulators will happily produce the right result if you enter a value of resistance that is negative. | |
| Oct 31, 2018 at 12:51 | comment | added | Marcus Müller | "this requires a negative resistance implementation": huh, how so? There's definitely no negative resistance in your circuit (but your semiconductor device might have operating points where more voltage means less current) | |
