The transistor fundamentally amplifies current but it can be connected in circuits designed to amplify voltage or power. The current flowing in the base circuit affects the current flowing between the collector and the emitter. Read . . . . more in-depth bipolar junction transistor theory.

What is the function of transistor?

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. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.

What are the two main uses of a transistor?

The core use of transistors include switching applications or both as amplification and switching.

Is 2N3055 a BJT?

What is the purpose of equivalent circuit?

Equivalent Circuit. Equivalent circuits are used in order to approximate the experimental impedance data with the above-mentioned ideal or distributed impedance elements, both arranged in series and/or in parallel. Many electrochemical systems have been analyzed according to this procedure.

When was the first junction transistor invented?

Shockley applied for a patent on the junction transistor that June and published his detailed theory of its operation in 1949. Still, it was two more years before Bell Labs scientists and engineers developed processes that allowed his junction transistor to be manufactured in production quantities (1951 Milestone).

What is the theory of transistors and other semiconductor devices?

Theory of Transistors and Other Semiconductor Devices. 1. SEMICONDUCTORS 1.1. Metals and insulators. 1.1.1. Conduction in metals. Metals are filled with electrons. Many of these, typically one or two per atom in the metal, are free to move about throughout the metal.

Can we improve transistor structure based on the p-n junction effect?

William Shockley conceives an improved transistor structure based on a theoretical understanding of the p-n junction effect. © 2006-2007 Alcatel-Lucent. All rights reserved
