Document Summary
In the mosfet reverse bias occurs on the right side from p n. Mos capacitor with positive gate bias use graph with ena, - ena, ena, -end where cuz its ptype the answer is ena. This can be figured out using the graph with the 2 squres. Clicker question when you increase the gate voltage to nmos gate, the drain current will increase because the conductivity of the region under the substrate oxide interface increases. If you do r = l/0a, and we increase the value of 0 which is the conductivity, the r decreases and we do v = ir, then. When you increase the drain voltage to nmos the drain current will increase because the electrons are drifting faster. Types of mosfet the enhancement (normally off) mosfet has a broken line in the diagram. Clicker a pmos has a p-type drain and source. Vgs is the voltage between the gate.
