Yep. The standard cascoding stuff also works. ...Jim Thompson

I love to cook with wine.     Sometimes I even put it in the food.

There are also family members that have PNPs

AFAIR it is a SOI die with 4x4 transistors and the subtypes are just bondout options. It is one of the very few fast PNPs that one can get space-qualified. I'm glad that it's there, even though building Wilson current mirrors requires 50R base stoppers. Especially in the fat hermetic flatpack that adds long leads.

I wished there was a PNP BF640!

Interesting. So there are actually 16 devices on the chip. You could make a lot of interesting things out of that, if they'll sell the bare dice. A real discrete designer's toolkit.

One of these days I'm going to have to get a wire bonder. Maybe once that quantum computing gig starts up (hopefully next month) I can find an excuse to use one of theirs.

Cheers
