Similarly, the Collector region “collects” those charge carriers and proceeds further. Emitter is the source of injecting the majority of charge carriers into other regions. ![]() Just as the name suggests, the Emitter region is responsible for “emitting” the charge carriers. There are three terminals of the BJT transistor: Bipolar Junction Transistor is a current-controlled device because the output collector current I C is an effect controlled by the input current. Most of the time, BJT is simply called a transistor because of its basic operation. Mostly every transistor falls into the category of either the junction or field-effect transistor.Ī Bipolar Junction Transistor (BJT) is a three-terminal semiconductor device used for switching purposes. Junction transistors operate on the basis of the junctions formed while field effect transistors perform due to an electric field. The main categories are junction transistors and field effect transistors. BJT, MOSFET, JFET - see more in figure 1) present in the market to serve a variety of applications. There are many different types of transistors (e. The enhanced signal with improved voltage/current/power appears at the output of the transistor amplifier device. A transistor amplifier enhances the strength of a small and weak signal. Another application of transistors is amplification. Such a solid-state switch uses transistors in cut-off and saturation regions. Depending upon the range of operation, a transistor can be used as a switch that turns on and off. The basic function of a transistor is switching and amplification. The transistor’s significance is evident from its inclusion in the IEEE list of historical achievements in the field of electronics. Hence, most transistors are controllable devices. Usually, one terminal of a transistor is a “control” that controls another terminal. What does a transistor do?Ī transistor has three terminals (sometimes four) - one input, one output, and a common terminal. ![]() The size of a transistor is merely a few millimetres as a discrete device and about nanometres when fabricated on a microprocessor chip. In short, the transistor is transferring resistance between the input and output of a circuit. A transistor transfers the resistance in the input circuit to a high/lower resistance value at the output. The word "transistor" is a combination of "transfer" and "resistance", meaning "transfer of resistance". A transistor is a small three-terminal semiconductor device used for switching and amplification purposes. ![]()
