共射放大器 [gòng shè fàng dà qì]
[电子] grounded emitter amplifier
- 要证明的那样，这一额外的电流镜射作用也改善了运算放大器的增益和共模输出阻抗。
in Sections II and III, this additional current mirroringaction also improves the gain and the common-mode output impedance of the op amp. - 系统性分析了电容耦合基本共射放大器的频率特性，得到了比较完整的频率特性函数和波德图。
Frequency characteristic of capacitor-coupled basic common-emitter amplifier has been analyzed, the complete frequency characteristic function and Bode diagram are given. - 低噪声放大器接收机中的重要部分之一，其噪声特性将大大影响整个系统的噪声性能，采用低噪声、高增益的共射-共基电路来实现低噪声放大。
its noise characteristic will greatly affect the noise performance of the receiver. LNA is carried out by the low noise common emitter-common base circuits.
