- reverse biased current 反向偏置电流
- As long as the base-collector junction remains reverse biased, increasing base current will cause a corresponding increase in collector current, and the transistor remains in active mode. 拟译:只要基极-集电极还处于反偏状态,上升的基极电流就会相应地引起集电极电流的上升,此时的三极管仍处于放大状态。

- The displacement current mechanism is operative only for capacitors under reverse bias or very weak forward bias conditions which maintain a space-charge layer. 位移电流的机理只对反向偏压或要维持空间电荷层所需要的非常弱的正向偏压条件下的电容器才有用。
- I added a switch that allows the bias current to be changed. 我加了一个开关来改变偏置电流。
- What's not so well known is that some ordinary NPN transistors such as the 2N2222, 2N3904 and 2N4401 exhibit negative resistance when reversed biased. 但是,却很少有人知道,一些普通的NPN三极管,如2N2222、2N3904 和 2N4401,在反向偏置时也表现出负阻特性。
- The photo-current was found to closely follow the eletro-absorption at large reverse bias values. 在很大的反向偏压下,光电流紧随着电吸收发生变化。
- Another consideration when measuring voltages from high resistance sources is the input bias current of the voltmeter. 在测量高电阻源时要考虑的另一个问题是电压表的输入偏置电流。
- During IGBT is off, the gate should be provided reverse bias voltage for ensuring the safe of IGBT. 在IGBT关断期间,IGBT的栅极需加反向偏置电压,避免IGBT的误动作。
- However, also consider amplifier noise, input bias current, offset voltage, MDAC resolution, and glitch energy. 然而,也要考虑放大器的噪声、输入偏置电流、偏置电压、MDAC分辨率和毛刺能量等因素。
- The gain of the APD can be controlled by the magnitude of the reverse bias voltage. APD的增益可以由反向偏置电压的幅度来控制。反向偏置电压越大增益就越高。
- Judgment is often biased by interest. 判断往往因利害关系而产生偏差。

- The silicon light emitting device also can be used as a photoreceiver under reverse bias, receiving the light emitted from the other one. 此发光元件在反偏下也可当成光接收元件,接收来自同结构顺偏元件所发出的光。
- The DAC transfers the data stored in EPROM to the gate of MOS transistor so as to control the bias current, and tune the responsivity of detector and dummy detector. 用数模转换器将存储在EPROM内的偏置电压输出到MOS管的栅极上,实现对偏置电流的控制,调节探测元及补偿元的响应率。
- Typical stressing like under the E-B reverse biasing results in some traps near the E-B spacer oxide and interface states in EB junctions. 传统的反向偏压射极-基极接面驱迫所造成的热载子会在靠近基极和射极接面以及隔离基极-射极的绝缘层上产生接面陷阱(traps)和带电荷的接面能态(interfacestate),而影响其直流特性上的电性反应。
