查询词典 emitter

It can be seen that besides the realization of the common-emitter gain, thus current amplification, the common-base properties were also improved due to the reduction of the common-base leakage current. We have attributed the improvement of the common-base properties and the realization of the common-emitter properties to the enhancement of the electron injection due to the utilization of the V2O5 interfacial layer.

研究发现，V2O5界面修饰层的引入明显地减小了共基极漏电流，使器件的共基极特性得到了进一步的改善，同时也使器件表现了共发射极特性，实现了电流的放大，我们已经把共基极特性的改善和共发射极特性的实现归功于界面修饰层的引入提高了电子注入的结果。

Following this rationale, if we were to hold the base-emitter voltage of a transistor constant, then its emitter current should likewise be constant, given a constant temperature

根据这个基本原理，如果我们能保持晶体管发射结电压恒定，当温度恒定时，发射极电流也将保持恒定。

CNT emitter has larger emission current than silicon-based emitter due to its high aspect ratio geometry. The results show that emission mechanism follows the Fowler-Norheim law.

从模拟结果我们可以看出场发射机制确实有遵守Fowler-Norheim规则，奈米碳管和矽基场发射器之间的差异，主要是奈米碳管其高深宽比的几何形状所导致较大表面电场会喷出较大的电流。

Well, the α ratio works similarly: if emitter current is held constant, collector current will remain at a stable, regulated value so long as the transistor has enough collector-to-emitter voltage drop to maintain it in its active mode.

系数α的作用与之类似：如果发射极电流保持恒定，只要集电极－发射极电压足以使其保持在放大区，集电极电流也将稳定保持。

If you change the diode current by changing the resistance value of Rbias, then the transistor's emitter current will follow suit, because the emitter current is described by the same equation as the diode's, and both PN junctions experience the same voltage drop.

正因为发射极和二极管的电流用同一个方程描述，而且两个PN结共用同一个电压，每当你通过改变Rbias改变了晶体管电流，晶体管发射极电流也必将随之同样改变。

In paper the phase noise L of the transistor is taked as function of Te, Re and R_(L1) for the first time, where Ie is emitter current, Re is resistor of emitter degeneration feedback and R_(L1) is aseismatic resistor on the collector.
