Fundamentals of Electronic Technology (III)_ Integrated operational amplifier and its application__ Basic arithmetic circuit

All kinds of operational circuits can be formed by using an integrated operational amplifier connected to an appropriate negative feedback circuit , There are mainly ：

1. Scale operation
2. Addition operation
3. Differential operation ( Subtraction )
4. integral 、 Differential operation

 

Differential and integral circuits are often used to realize waveform transformation .  Differential circuit can convert square wave voltage into sharp pulse voltage , Integrating circuit can convert square wave voltage into triangular wave voltage .
