An amplifier that uses Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) technology is known as a MOSFET amplifier. MOSFET is also called the MOS (metal-oxide-silicon) transistor and it is one kind of insulated-gate field-effect transistor. So this transistor is fabricated through silicon...
How does Mosfet work as an amplifier? The advantage of the voltage divider biasing network is that the MOSFET, or indeed a bipolar transistor, can be biased from a single DC supply. Therefore if we apply a small AC signal which is superimposed on to this DC bias at the gate input, then...
MOSFET is a FET with an insulated gate where voltage determines conductivity of the device and is used for switching or amplifying signals.

Here is an audio amplifier using PUSH PULL mode to drive a speaker: The top two transistors are in push-pull mode to turn the P-channel MOSFET on and off very quickly. They speed up the incoming waveform and prevent the MOSFET generating heat during the turning-on process. ...
To deactivate a P-channel depletion MOSFET, there are two ways you can cut off the bias positive voltage, that powers the drain otherwise you can apply a -ve voltage to the gate terminal. Once a -ve voltage is provided to the gate terminal, the current will be decreased. As the gate ...
(Continuous Current Mode) operation has been implemented to achieve lower conduction losses, thereby achieving a higher efficiency to meet international regulatory standards. To further reduce BOM count and cost of a non-isolated flyback design, an integrated error amplifier is integrated to allow a ...
They are widely used as an amplifier, switch or oscillator. It is a current-controlled device, meaning that the amount of current flow between the emitter and collector is controlled by the base current. MOSFET – Metal Oxide Semiconductor Field Effect Transistors ...
