Non-Inverting Op Amp

“How can we make an Op-Amp amplifier without inverting the output?”

 

Inverting Op-Amps are great for changing the sign of a signal, However, sometimes we would like to simply amplify instead of invert. So how can we accomplish this using our engineering mindset? Well, What if we were to simply reverse the inputs to the op-amp? That way, we can create a Non-Inverting Op Amp, whose gain is represented by 1+R2/R1, with R2 being the second resistor and R1 being the first.
