| 摘 要： | 以共射放大电路的各种幅频特性曲线为例,判断放大电路的构成,需讨论几个问题:放大电路由几级耦合电路组成,影响电路特性的电容分布情况,每级的下限和上限截止频率是多少;总的下限和上限截止频率fL和fH是多大;电路总的电压增益Aum、电压放大倍数的表达式.结果表明,多级放大电路的波特图是各放大级波特图的叠加.

| Abstract: | Taking various curves of megascopical circuit as the case,the estimation of the composition of megascopical circuit should pay attention to the following problems:what level coupling circuit compose the megascopical circuit,and its influence on the capalitance distribution,what are the close frequency of the upper limit and lower limit of every level,etc.The outcome show that,the Baut chart of multi-level megascopical circuit is the splice of every megascopical Baut chart. |
