基本放大电路的输出电阻计算较为复杂,常常要用到基尔霍夫电流定律和基尔霍夫电压定律,涉及的电路知识较多。文章采用的利用受控源的电阻性求解输出电阻的方法,只需要欧姆定律和简单的电阻串并联知识就可以解决。
The basic amplifier circuit output resistance calculation is more complicated, and often need to use Kirchhoff’s law of current and Kirchhoff’s voltage law, the circuit involved more knowledge. The method used by the article to control the output resistance of a controlled source using resistive solutions requires only Ohm’s law and a simple parallel knowledge of resistor series.
