| 摘 要： | 多级放大器的放大倍数的计算有两种基本方法，但当多级放大器中含有双入双出型差动电路时。两种方法可能会带来不同的计算结果．本文从差动电路的交流通道出发，提出了将负载效应均分在电路两侧的观点，对计算结果进行了修正．

| Abstract: | There are two methods to calculatie the gain in multistage amplifier. When multistage amplifier has double-input double-output differential circuit, the two methods produce different calculating results. In this paper, alternating passage is used in the differential circuit analysis, and load effect is divided equally at two sides of the circuit, and satiSfactory resultis obtained. |
