从集成运放比例运算电路的分析结论出发 ,进行一般反相放大、同相放大和差分放大电路的通用结构及其频域分析 ,得出更具有一般性的归一化结论 ,使典型放大电路的分析过程大为简化 ,为频域综合提供了可行的途径。 Based on the analysis of the integrated op amp operation circuit, the general structure of the inverting amplifier, the noninverting amplifier and the differential amplifier and their frequency domain analysis are analyzed. The more generalized normalization results are obtained, The analysis process is greatly simplified, providing a feasible approach for frequency domain synthesis.
