negative-feedback amplifier

基本解释

The input and output resistances of a negative-feedback amplifier is calculated by analytic method.
根据电路原理，应用解析方法导出了四种形式负反馈放大器的输入、输出电阻关系式。
At the power output, OCL complementally and symmetrical power amplifier is adapted. The output sine voltage becomes smooth and stable by adding voltage-negative-feedback to power amplifier.
在功率输出级采用OCL互补对称功率放大电路，并对该功放电路增加电压负反馈，使得输出的正弦电压信号平滑而稳定。
The article analyzes the frequency characteristics of RC series parallel circuits and the symmetrical circuits, through studying the effectiveness of the positive-negative feedback to the amplifier.
