What are the two states of a transistor?
In an ideal switch, the transistor should be in only one of two states: off or on. The transistor is off when there’s no bias voltage or when the bias voltage is less than 0.7 V.
What is active state of a transistor?
If the bias of the emitter-base junction of a transistor is sufficient to send a forward current and the collector base junction is reversed biased, the transistor is said to be in the active state.
At what state is a transistor said to be saturated?
A transistor goes into saturation when both the base-emitter and base-collector junctions are forward biased, basically. So if the collector voltage drops below the base voltage, and the emitter voltage is below the base voltage, then the transistor is in saturation. Consider this Common Emitter Amplifier circuit.
What are the three states of a transistor?
To be very specific, a transistor actually does have 3 states: cutoff, triode, and saturation. For use in digital circuits (aka computers), transistors operate in the saturation state, which allows them to essentially act as an “on or off” switch. This is how digital circuits are designed to be physical…
What is the purpose of a transistor in electronics?
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. Transistors are one of the basic building blocks of modern electronics.
How is the gate separated from the body of a transistor?
Metal-oxide-semiconductor field-effect transistor (MOSFET), showing gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (pink). A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.
What kind of material is a transistor made out of?
Transistors revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. Most transistors are made from very pure silicon, and some from germanium, but certain other semiconductor materials are sometimes used.
