摘　　要：通过系统分析多级放大级联的增益与带宽的理论研究和计算公式推导,总结出多级放大器的增益和带宽的计算公式并给出公式的相应算法程序。同时通过列举实例,利用TI的TINA仿真设计软件,设计相应电路,经过仿真分析,对理论成果进行了验证。Based on the theory and formula derivation of the gain and bandwidth of multi - stage amplifier, this paper summed up the formula of the gain and bandwidth of the multi-level amplification and give out the formula in the corresponding algorithm. At the same time, we designed corresponding circuit as the examples. The simulation was designed by using the software TINA, the theoretical resuits were verified.
