Apply KCL at the node at the inverting input to the amplifier - the red dot. ... Well, what you have learned in this lesson is that the Nyquist stability criterion can be applied to operational amplifier circuits. In the process you should see that you may not want to believe the conclusions you would draw from the infinite...

When the polarity of the differential voltage matches the markings for inverting and noninverting inputs, ... The operational amplifier is arguably the most useful single device in analog electronic circuitry. With only a handful of external components, it can be made to perform a wide variety of analog signal processing tasks.

With a higher voltage gain, this circuit is able to function as a working operational amplifier, or op-amp. Op-amps form the basis of a great many modern analog semiconductor circuits, so understanding the ... To make a voltage follower circuit, directly connect the output of the amplifier to its inverting input.

Analog Integrated Circuits ... An ideal operational amplifier may be simulated in SPICE using a dependent voltage source (e1 in the netlist). The output nodes are specified first (2 0), then the two input nodes, non-inverting input first (1 2). Open-loop gain is specified last (999meg) in the dependent voltage source line.
