Capacitive Coupling in a Semiconductor
Capacitive Coupling in a Semiconductor
(OP)
Hello,
I have a dual, N-channel MOSFET die in one package, and I need help in trying to figure out how to measure the capacitive coupling of these two die. The configuration is not one dual monolithic die, but rather two different N-channel MOSFET die in a single package.
Someone mentioned applying a step voltage across one MOSFET, and see how the current changes in the other, based on: i = C (dv/dt)
Now, where would the step voltage applied to: the gate of one MOSFET?
And then measure the drain current of the second MOSFET?
Thanks,
AD25

RE: Capacitive Coupling in a Semiconductor
What you've proposed will most likely fry your device before you get a good measurement from it. Also, had you looked at the datasheet for the part?
