“How can we invert a voltage using an Op-Amp?”

 

A circuit’s operations are dictated by its voltage levels. However, sometimes we may just want to invert the sign. So how can we accomplish this using our engineering mindset? Well, what if we were to attach our circuit to the inverting input of an op-amp, attach the other input to the ground, and fasten another resistor after the first input? That way, the voltage in between the two resistors be grounded, and the voltage at the output of the next resistor would have its sign reversed. Well, this is the fundamentals behind something known as an inverting op-amp and is used in low-noise amplification.
