For example, the non-inverting summing amplifier with two inputs has on one input the control signal and, on the other one, the inverted feedback. The weighted sum also gives the designer the opportunity to adjust the feedback versus the control signal. Moreover, dynamic compensations can be achieved easily. More on this subject in a future article. Yes, the summing amplifier is used as an error amplifier in many systems.

Can you please explain how you calculated that circuit? You posted the solution of a circuit in this forum,

Now it looks so simple. Great post, by the way. I’ve being trying to solve this for a while, until I noticed your post. Now it looks so simple. Great post, by the way.
