摘要
本文推导了同相型运算放大器输入电阻的精确表达式 ,并指出有关文献中的输入电阻的几种表达形式均是精确式在不同近似条件下的近似式。
The accurate expression of input resistor of non-inverting operational amplifier is deduced in the paper. It is pointed out that some expressions of input resistor in the relative references are all approximate to the accurate expression under different proximal conditions.
