I was asked that there is a nmos with Vth=1V, gate voltage Vg=3V. One end of the nmos node B (source/drain) is connected with a small capacitor (almost instantly charged), and the other end node A (source/drain) is swept from 0V to 3V.
Question: How is the voltage at node B changed as node A ramping from 0V to 3V?
Thanks ahead for answering my question.
