How to use virtual short and virtual break to troubleshoot the cause of circuit abnormality?

Operational amplifiers are very important components in analog circuits. They can form various circuits such as amplification, addition, subtraction, and conversion, and are widely used in circuit design. So, if the circuit is abnormal, how should we check whether it is the cause of the damage to the operational amplifier? That is to use the “virtual short” and “virtual break” … Continua a leggere
