摘要
用方框图分析法分析了由集成运算放大器构成的4种负反馈放大器的性能,包括输入、输出电阻和增益。导出了可用工程计算和设计的一组近似公式。讨论了集成运放和电路元件参数对负反馈放大器的影响,并与理想运放分析得出的结果进行了比较。
Characteristic analysis for the integrated operational amplifiers with negative feedback configuration by means of block diagram topology is described. A set of satisfactory approximate expressions for engineering design are achieved. We also discuss the influence on the negative feedback amplifier properties due to perameters of nonideal OP Amp and the circuit components and compare the analytical results with those of the ideal Op Amp. Key words:integrated operational amplifier; negative feedback; analysis method of block diagram topology
