I have this project where I need to generate at least 200V and probably more around 900V, but I only need about 1mA maximum in current (probably less).
The other requirement is that at least one dimension on the device needs to be less than 1cm.
So the question is, what can I do (or buy) to obtain this voltage?
My thought was possibly some kind of charge pump, or multiple charge pumps in series.
(yea, yet another strange question that Im not allowed to elaborate on)
