Why is Darlington array not as efficient as MOSFET as a stepper motor controller?

It is due to the saturation voltage of Darlington pairs, which is normally 1 V. With a load of 1A, the device consumes 1 W. Quite a challenge for c

Why do we use an insulating layer between the gate electrode and the channel region for a MOSFET?

A layer of silicon oxide (SiO 2) typically grows on a silicon substrate and a metal or polysilicon layer is deposited over it. If you observe, this ac

Is MOSFET a bidirectional device or unidirectional device What is a clear explanation about this?

The MOSFET is a symmetrical device in which the source and drain can be interchanged (if the body is not short-circuited to the drain or source). The
