Note that the SFG may be easier to understand than a description or set of equations. Also note that the op amp SFG signals propagate from input to output. This is a simple circuit with no interaction. WebThe op amp is designed to detect the difference in voltage applied at the input (the plus (v2) and the minus (v1) terminals, or pins 2 and 3 of the op amp package). The difference is also known as the differential input voltage. The output, then, is the difference sensed at the input multiplied by some value A - the open-loop gain. highway to healing sanford nc
