How do MOSFETs and field-effect transistors work?

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. The most widely used field-effect transistor is the MOSFET (metal-oxide-semiconductor field-effect transistor).

Why we use MOSFET over BJT?

Mosfet provides a very good isolation between the gate and the other two terminals compared to bjt. MOSFET can handle more power compared to BJT. The mosfet has a very low power loss and a high speed. Voltage signals can easily operate a mosfet, so it is used in many digital circuits.

What is the difference between a MOSFET and a BJT?

The Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) and the Bipolar Junction Transistor (BJT) are two types of transistor that come in various packages, and those unfamiliar with electronics often struggle to decide which should be used in their projects.

How does a MOSFET work?

MOSFET is a kind of field effect transistor (FET) that consists of three terminals – gate, source, and drain. In a MOSFET, the drain is controlled by the voltage of the gate terminal, thus a MOSFET is a voltage-controlled device. The voltage that is applied across the gate controls how much current flows into the drain.

What type of transistors are used in microchips?

For modern microchips, the transistors are of the kind called Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), and the semiconductor used is silicon. A MOSFET has three components, or regions: a source region, a drain region and a channel region having a gate over it.

What makes up a logic gate in a microchip?

“A logic gate in a microchip is made up of a specific arrangement of transistors. For modern microchips, the transistors are of the kind called Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), and the semiconductor used is silicon.
