What is a transistor?
What is a Transistor? A transistor is a type of a semiconductor device that can be used to both conduct and insulate electric current or voltage. A transistor basically acts as a switch and an amplifier.
What is the difference between CB and CC in transistors?
In Common Base (CB) configuration the base terminal of the transistor is common between input and output terminals. In Common Collector (CC) configuration the collector terminals are common between the input and output terminals.
What is an emitter in a transistor?
Emitter: It is the negative lead of the transistor. Well, the very basic working principle of a transistor is based on controlling the flow of current through one channel by varying intensity of a very smaller current that is flowing through a second channel.
What is a MOSFET transistor?
The MOSFET (metal–oxide–semiconductor field-effect transistor), also known as the MOS transistor, is by far the most widely used transistor, used in applications ranging from computers and electronics to communications technology such as smartphones.
It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor’s terminals controls the current through another pair of terminals.
How does a bipolar transistor work?
The image represents a typical bipolar transistor in a circuit. A charge will flow between emitter and collector terminals depending on the current in the base. Because internally the base and emitter connections behave like a semiconductor diode, a voltage drop develops between base and emitter while the base current exists.
What is the difference between a gate and a transistor?
The gate is separated from the body by an insulating layer (pink). A transistor is a semiconductor device used to amplify or switch electrical signals and power. The transistor is one of the basic building blocks of modern electronics.
What is a phototransistor?
Devices designed for this purpose have a transparent window in the package and are called phototransistors . The MOSFET is by far the most widely used transistor for both digital circuits as well as analog circuits, accounting for 99.9% of all transistors in the world.
