A semiconductor device including a transistor, diode and resistor comprises a body of semiconductor material formed with conventional emitter, base and collector regions. The collector region forms one electrode of the diode with the other electrode being formed in the region forming the base of the...
既然是最基本的,那我就来讲讲diode吧! 首先,我们来看看一个diode为什么可以被看成是一个resistor。 咦?看起来似乎没有什么共通之处嘛! 好吧,我们换个角度再看看? 是不是觉得有些相似了? 其实一个电阻也是可以被看做是一个受控电流源的,它的gm是1/R. 同理,本征电阻ro也是可以被看做是一个受控电流源,它...

A resistor composed of polysilicon is connected to the base electrode connection region via a metal electrode . As a result, this semiconductor device has a bipolar transistor in which a zener diode ZD and the resistor are serially built into the base. 展开 ...
the differences between Vil and Vol, and between Voh and Vih, are much larger than those exhibited by RTL gates, wherein the collector of the driving transistor is directly connected to the base resistor of the driven transistor. This is why DTL gates are known to havebetter noise marginstha...
theForward voltageparameter, the diode behaves as a linear resistor with the resistance specified in theOn resistanceparameter. Otherwise, the diode behaves as a linear resistor with the small conductance specified in theOff conductanceparameter. Zero voltage across the diode results in zero current ...
A steady voltage is produced if the resistor's current flow is restricted. Zener diodes are frequently utilized in power supply to give a reference voltage. Schottky Diode It has a lower forward voltage than all other silicon PN junction diodes. Low current areas will show a drop, and ...
A Zener diode is an electronic component used in DC voltage regulator circuits. This calculator will calculate the maximum current and the necessary series resistance to protect the Zener diode.
