【電子工学/OPアンプ回路】031：帰還回路（OPアンプ非反転・反転増幅の帰還を徹底解説｜抵抗で決まる増幅度・出力強化の手法）

*Number 030 is missing. [Overview] This section carefully explains, using circuit diagrams and equations, how the resistors constituting the feedback circuit work and how they determine the amplification factor in non-inverting and inverting amplifier circuits of op-amps. Starting with an ideal op-amp model, the equations for non-inverting and inverting amplification factors are derived one by one, while tracing the current relationships of the feedback resistors and node voltages. Furthermore, a method for reinforcing the output stage with a push-pull circuit when the load is heavy and difficult to drive with an op-amp alone is introduced, and basic connection examples and operational images are explained.
