1. What are the main uses of MOSFETs?
As a switch: used to quickly turn a circuit on or off.
As an amplifier: amplifies signals in analog circuits.
As a power switch in applications such as power management, motor control, inverters, etc. -
2. How does a MOSFET work as an amplifier?
A MOSFET can change the resistance between the source and drain by adjusting the gate voltage, which in turn affects the current flowing through this path. This allows the input signal to be amplified.

3. What is the difference between a JFET and a MOSFET?
A JFET (junction field effect transistor) does not have an insulating layer between the gate and the channel, but instead has a PN junction.
JFETs generally only work in depletion mode, while MOSFETs can be of two types: enhancement mode and depletion mode.
The input impedance of a JFET is lower than that of a MOSFET. -
4. Is MOSFET 3-terminal or 4-terminal?
Basically, MOSFET is a three-terminal device (source S, drain D, and gate G). But in some cases, such as some high-voltage and high-power MOSFETs, there may be additional terminals (for example, substrate terminal B) to improve performance or reliability, so it is sometimes called a four-terminal device.
