- 摘要:
- 晶体三极管是重要的电子器件。为了更好地应用晶体三极管,必须对晶体三极管的各种组态分析清楚。晶体三极管具有三种组态,分别是共集电极放大电路、共基极放大电路、共射极放大电路。晶体三极管的主要参数有静态工作点、输出特性、输入特性、频率特性与放大特性。晶体管的静态工作点的设置对放大电路的正常工作至关重要,如果选择不恰当的静态工作点,输出信号将饱和失真或截止失真; 输入输出特性能够分析出三极管带负载的能力; 晶体三极管的频率特性表明了信号的通过性,对不同频率的信号具有不同的放大特性。对晶体三极管进行了简要概述,并针对性分析了共射极放大电路,即它的输入输出特性、放大特性。
- Abstract:
- Bipolar Junction Transistor is important electron device. Each part of Bipolar Junction Transistor should be analyzed clearly for better application. It has Three types of configuration, they are common collector amplification circuit, common-base amplification circuit and common emitter amplification circuit. Major parameters of bipolar junction transistor are quiescent operating point, output characteristics, input characteristics, frequency characteristic and amplification characteristic. Quiescent operating point of bipolar junction transistor is great important to amplification circuit. Output signal will saturation distortion or cut-off distortion when choosing an improper quiescent operating point. Output and input characteristics can provide the ability of bipolar junction transistor's operating load. Its' frequency characteristic can provide signal's trafficability characteristic and different frequency of signal has different amplification characteristic. This paper summarizes bipolar junction transistor's amplification characteristic and common emitter amplification circuit's output and input characteristic.
