Figure 12. This has some interesting implications a 3V motor can be driven using a 12V supply using a low duty cycle since the motor sees only the average voltage. For driving the MOSFET in high side configuration, IR2110 gate driver IC was used. For an example of a MOSFET driver, look at something like the Microchip TC1426. The field-effect transistor (FET) is a type of transistor that uses an electric field to control the flow of current in a semiconductor.FETs (JFETs or MOSFETs) are devices with three terminals: source, gate, and drain.FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source. Mosfet is a good choice for building linear amplifiers owing to its lesser load, and any amplifier made using it is called a Mosfet amplifier.
