I stumbled upon a weird transistor or resistor component which I can't place. Here is a simplified version of the circuit:
I am pretty sure that the transistor on the bottom is an N-MOS transistor which pulls
out low if
in is high. The weird component at the top seems to serve as pull up resistor but looks more like a transistor than anything.
Can someone identify the component?
Note: I saw the component on a presentation slide which I don't have access to. I had recreated the circuit from my notes, and thus can't provide more information.
