Hi to everybody!
This is my first post as a registered member here.

I have a question that I was not able to solve searching past threads (nor with google :roll:).

I know that a thyristor can be built joining two BJTs. Is it also possible to build it with FETs?
In particular, I would like to know if it is possible to make up a bistable switch (this is why I was looking for thyristors) using thick film transistors (OFETs) like the ones used in PC monitors' backplanes.

Something like a "solid state latching relay": when there is no command, it keeps the last state, while if a command is applied it triggers from on to off or viceversa.

Any idea?
 

Is the question badly posed or is it just too silly? :oops:
 

It may be either, both or neither. It's probably because no one (including me) has ever investigated something like it. And the idea is unconventional enough that no one can immediately come up with an opinion either way. It would be rash to say that it's impossible, and at the same time no usable scheme comes to mind.
 

Thank you for the feedback Pjdd!
I am still investigating this problem: if I'll be able to gather more data or (quite unrealistic :roll:) to find a solution, I will update the thread!
