Transistor , semiconductor device for amplifying, controlling, and generating electrical signals. Deeply embedded in almost everything electronic, transistors have become the nerve cells of the Information Age.

Definition: The transistor is a semiconductor device which transfers a weak signal from low resistance circuit to high resistance circuit. The words trans mean transfer property and istor mean resistance property offered to the junctions. In other words, it is a switching device which regulates and amplify the electrical signal likes voltage or current.

Definition of Power Amplifier and Its Classification. Warm hints: The word in this article is about words and the reading time is about 15 minutes. I What is Transistor? II Development of Transistors. III Classification of Transistor. IV Main Parameters of Transistors. This article will mainly introduce what exactly a transistor is and its detailed characteristics and functions.

They are used in a variety of circuits and you will find that it is rare that a circuit built in a school Technology Department does not contain at least one transistor. Most circuits tend to use NPN. There are hundreds of transistors which work at different voltages but all of them fall into these two categories. The BASE - which is the lead responsible for activating the transistor. The diagram below shows the symbol of an NPN transistor. The leads on a transistor may not always be in this arrangement. A small current or voltage at the base allows a larger voltage to flow through the other two leads from the collector to the emitter.

Different Types of Transistors and Their Functions

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. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled output power can be higher than the controlling input power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.

The transistor is an active component and that is establishing all over electronic circuits. They are used as amplifiers and switching apparatus. As the amplifiers, they are used in high and low level, frequency stages, oscillators, modulators, detectors, and in any circuit need to perform a function. In digital circuits, they are used as switches.

What are the Two Main Types of Transistors?

 Чед! - рявкнул у него за спиной Фонтейн. Директор наверняка обратил внимание на выражение глаз Мидж, когда она выходила.  - Не выпускай ее из приемной. Бринкерхофф кивнул и двинулся следом за Мидж. Фонтейн вздохнул и обхватил голову руками. Взгляд его черных глаз стал тяжелым и неподвижным. Возвращение домой оказалось долгим и слишком утомительным.

Она металась между дверцами кабинок и рукомойниками. Потеряв ориентацию, двигалась, вытянув перед собой руки и пытаясь восстановить в памяти очертания комнаты.

Сердце у Сьюзан бешено забилось. Правильно ли она поняла. Все сказанное было вполне в духе Грега Хейла.

 Вы похожи на полицейского. - Слушай, парень, я американец из Мериленда.

Как только найдется недостающая копия ключа, Цифровая крепость - ваша. - Но с ключа могут снять копию. - Каждый, кто к нему прикоснется, будет уничтожен. Повисла тишина. Наконец Нуматака спросил: - Где ключ .

Поблагодарил меня за то, что я решил позвонить .

Сьюзан была убеждена, что это невозможно. Угрожающий потенциал всей этой ситуации подавил. Какие вообще у них есть доказательства, что Танкадо действительно создал Цифровую крепость. Только его собственные утверждения в электронных посланиях. И конечно… ТРАНСТЕКСТ.

Бесчувственная демонстрация силы страной, уже добившейся победы. С этим Танкадо сумел примириться.

    As the emitter current for a common emitter configuration is defined as. Ie = Ic + and is a function of the transistor itself (electrons diffusing across the junction).

    V CE is approximately equal to VCC — When the base-emitter junction is forward-biased and there is enough base current to produce a maximum collector current, the transistor is saturated.
