A simple circuit diagram showing the labels of an n–p–n bipolar transistor. A transistor can use a small signal applied between one pair of its terminals to control a much larger signal at another pair of terminals, a property called gain.
Cross-sectional view of a MOSFET type field-effect transistor, showing source, gate and drain terminals, and insulating oxide layer. The field-effect transistor (FET) is a type of transistor that uses an electric field to control the current through a semiconductor. It comes in two types: junction FET (JFET) and metal-oxide-semiconductor FET ...
Bipolar transistors, and particularly power transistors, have long base-storage times when they are driven into saturation; the base storage limits turn-off time in switching applications. A Baker clamp can prevent the transistor from heavily saturating, which reduces the amount of charge stored in the base and thus improves switching time.
There are three types of unijunction transistor: The original unijunction transistor, or UJT, is a simple device that is essentially a bar of n-type semiconductor material into which p-type material has been diffused somewhere along its length, fixing the device parameter (the "intrinsic stand-off ratio"). The 2N2646 model is the most commonly ...
A simple schematic showing wires, a resistor, and a battery The basic components of analog circuits are wires, resistors, capacitors, inductors, diodes , and transistors . Analog circuits are very commonly represented in schematic diagrams , in which wires are shown as lines, and each component has a unique symbol.
The junction field-effect transistor (JFET) is one of the simplest types of field-effect transistor. [1] JFETs are three-terminal semiconductor devices that can be used as electronically controlled switches or resistors , or to build amplifiers .
The first transistor hi-fi system was developed by engineers at GE and demonstrated at the University of Philadelphia in 1955. [9] In terms of commercial production, The Fisher TR-1 was the first "all transistor" preamplifier, which became available mid-1956. [10] In 1961, a company named Transis-tronics released a solid-state amplifier, the ...
CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", / s iː m ɑː s /, /-ɒ s /) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.
