Document Summary
Ece 207 -- exam 3 formula sheet in above: r(input) = v(i) / i(1) = 2 kohms. Usually, this feedback condition exists when the output signal is connected to the inverting input of the op amp via some kind of resistor network. (output connected to input is feedback: be able to recognize a positive feedback circuit, understand that with a positive feedback circuit, the output will be either at the positive supply voltage (rail) or the negative supply voltage (rail), understand the summing point constraint (vd = 0 and currents into op amp input terminals are zero).

Ece 207 -- exam 3 formula sheet algebra/handwaving happens and: Why is gain not dependent on r3 or r4: r4/r3 = r2/r1.
