Based on the model, the variations of the electrical parameters such as the potential barrier, the anode junction voltage drop, and the current amplification factor are studied and discussed. 在该模型的基础上,讨论了势垒、阳极结的电势降落和电流的放大因子等电参数的变化。
The experimental results showed that the light current Ip, current amplification factor β and response time to photo-devices were all decreased while dark current Id increased and junction capacitance C unchanged basically. 结果表明,γ辐照使光敏器件的光电流Ip、电流放大倍数β和光电响应时间t减小,暗电流Id增加,结电容C基本不变。
Analysis of the current amplification factor of emitter follower 射极输出器电流放大倍数的分析
At a higher injection level, the current amplification factor drops off as the emitter current density is increased. 一个是在给定的注入条件下如何保证足够大的电流放大;
