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。
The presence of a large density of contaminant causes anomalous increases in the diode current with increasing reverse bias . 大量沾污也会使二级管电流随反向偏压的增加而呈现反常的增大。
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。
Devr - v series high - temperature reverse bias burn - in system Devr - v系列高温反偏老化系统
Zero adjustment function , forward adjust is forward biased , reverse adjust is reverse biased 零点调整功能,顺时针调整可以偏负,逆时针调整可以偏正。
The high efficiency and high power semiconductor laser with multi - active regions , which are cascaded by reverse biased tunnel junction ( s ) can resolve the problems in theory and overcome these shortcomings 通过反向偏置隧道结将多个有源区再生耦合级联起来的新型高效大功率半导体激光器从理论和实践上解决了传统激光器存在的上述问题。
In normal operation the diode is reverse biased and contributes only its ( low ) leakage current to the circuit but should the sensor be short - circuited the resulting current will flow through the diode to the op - amp supply rather than destroy the op - amp 正常情况下,二极管处于反向偏置,只有很小的漏电流;当输入端窜入高压时,二极管正向导通泻放掉大电流,保护放大器。
In view of the very small leakage currents in the blocking state ( reverse bias ) and the small voltage in the conducting state ( forward bias ) as compared to the operating voltage and currents of the circuit in which the diode is used , the i - v characteristics for the diode can be idealized 与二极管的工作电流和电压相比,在阻断(截止)状态下漏电流很小,在导通状态下电压比较小,因此二极管的电流-电压(伏安)特性可以理想化。
The usual method to broaden the bandwidth of the pin diode switch is combining the pin diodes with stub filters : when under reverse bias , the didoe is part of the filter , the transmission bandwidth is broadened ; when under forward bias , the structure of the filter is destroyed , signal is isolated Pin二极管开关展宽频带的方法一般是把pin二极管结合进短截线滤波器,使pin二极管在反向偏置时作为滤波器的组成部分,以展宽开关在传输状态下的频带;当二极管正向偏置的时候,滤波器的结构被破坏,起到隔离的作用。
