OpAmp "Non-standard" Feedback Hello, This is my first post here. Please excuse my poor English and grammar. I will try to make my questions clear. As I understand, with a negative feedback, where the output connected to the inverting input and in the ideal case, the Vn and Vp will be very close in a sense that Vn tracks the voltage of Vp so that the difference is almost zero. However, when changing the feedback configuration, for example connecting the Vn input to other parts than the output, or using a positive feedback, how does this affect the ideal rules in analysis? Thanks.
