I see, that your answer confirms my previous assumption: "It depends" - We can make W/L sufficient small to avoid unsafe currents. But how about a reasonable circuit purpose?

What is it good for?

Hi FvM,

The purpose is not served but it was an interview question to me .

I think, the keyword "interview" should be mentioned with the question.
It enables edaboard members to switch to the "meaningless and hypothetical questions" mode. :smile:

But the question has been in fact answered. You can expect a voltage >0, depending on the actual transistor parameters.
 

indefinite op can be any piece of crappy op voltage which is not based on any criteria or rules of the circuit

it can be 0 V at the least to the destruction of the MOS which is the least possible event
