关于差分式放大器输入电阻的研究

Research into the input resistance of differential amplifier

差分式放大器在实际应用方面非常广泛,其理论分析方法的深入研究,对生产实践和教学都有重要的意义。采用电路理论分析、差放理论分析、“虚短”理论分析及实验的方法对差分式放大电路进行了研究。

Differential amplifiers find wide applicatien. The further research into the theoretic analysis method is of great significance to the production practice and teaching. Research is made into the differential amplifier circuit by means of circuit theory analysis, differential amplifier theory analysis, ＂virtual - short＂ theory analysis and experiment way.
