it can be used as a sort of current-controlled switch.A relatively small flow of electrons sent through the base of the transistor has the ability to exert control over a much larger flow of electrons through the collector.
In some transistors, the outer layers have an excess of electrons; in others, the middle layer has more electrons. Transistors work like gates, allowing or closing off the flow of electrons when an electric current or voltage is applied to a particular layer. Because of their tiny size and ...
9. The operation of two-Transistor forward converter toponology and current control mode are discussed in this paper. 文章详细研究了双管正激变换器的拓扑结构及工作原理,阐述了该拓扑结构的优点及缺点。 10. transistor的意思 10. SENDON GENIUS UPS uses IGBT(insulated gate bipolar transistor) technology ...
MOSFETs are voltage-controlled devices (Sze 1990) in which a metal electrode placed on top of an insulator (typically SiO2) on the silicon surface is used to control the flow of current between two ohmic contacts on the silicon. From: Encyclopedia of Materials: Science and Technology, 2001 ...
The meaning of TRANSISTOR is a solid-state electronic device that is used to control the flow of electricity in electronic equipment and usually consists of a small block of a semiconductor (such as germanium) with at least three electrodes.
The channel region (130) has a compressive stress (145) in a direction parallel to an intended current flow (125) through the channel region (130). Other embodiments of the present invention include a method of manufacturing the PMOS device (200) and a MOS device (300).BUSS DENNIS D....
NPN Transistor Definition: An NPN transistor is a widely used type of bipolar junction transistor, where a P-type semiconductor layer is flanked by two N-type layers. Symbol: The symbol for an NPN transistor shows the flow direction of the emitter current with an outward pointing arrow. Workin...
Strain in the channel occurs biaxially, that is, in directions parallel and perpendicular to the flow of current through the channel. In contrast, the use of biaxially tensile-strained-silicon in a P-type Metal Oxide Semiconductor (PMOS) transistor is much less beneficial. A PMOS channel ...
The second voltage component is of fixed magnitude and develops collector current (I.sub.0) flow through the transistor and thereby actuates constant-current source operation. The result is a transistor constant-current source that provides a constant output current independent of temperature. 展开 ...
Class-B amplifiers uses “Complementary” or “Matched Pair” (that is one PNP and one NPN connected together) transistors in its output stage or in reversible H-Bridge motor control circuits were we want to control the flow of current evenly through the motor in both directions....
