    Turning on a MOSFET takes more than knowing the threshold voltage. A special event occurs when a FET turns-on, which is called the Miller Plateau. The gate voltage sticks to the threshold voltage while the drain opens up. In this video, James shows how to measure the Miller Capacitance, using an oscilloscope and custom MOSFET test board.
