Hi!

I'm new here, with a basic question: I would liek to join, on the layout, the drain of two transistors that share the same drain

Here are the two transistors:

Can the drains be joined this way (is it correct?):

I've just moved one of the transistors in order to allign the contacts of the drain of both transistors, as shown above.

Is the method used correct or should I create, for example, an unique substract for both (how can I do it?) of them?

Best regards :thumbsup:

What you have done is correct. But if the transistors share both drain and source, then it is the source that gets preference in shared layout. And the drains are connected through routing.
