	Common Base 共射极

This configuration is used for high frequency applications because the base separates the input and output, minimizing oscillations at high frequency. It has a high voltage gain, relatively low input impedance and high output impedance compared to the common collector.

这种配置用于高频应用，因为基极将输入和输出分开，从而在高频下最小化振荡。它具有较高的电压增益，相对于共集电极配置，输入阻抗相对较低，输出阻抗较高。
