An op-amp has two inputs, an inverting terminal (labeled „-") and a non-inverting terminal (labeled „+"). And has a single output. The first input is called inverting because the output voltage is inverse of the voltage applied at the inverting input, times the gain of the amplifier circuit.If we apply the signal to the non-inverting input we get the same signal on the …

This intimidating circuit is constructed from a buffered differential amplifier stage with three new resistors linking the two buffer circuits together. Consider all resistors to be of equal value except for R gain. The negative feedback of the upper-left op-amp causes the voltage at point 1 (top of R gain) to be equal to V 1.
An ideal op-amp has infinite input impedance to prevent any flow of current from the supply into the op-amp circuit. But when the op-amp is used in linear applications, some form of negative feedback is provided externally. Due to this negative feedback, the input impedance becomes. Z in = (1 + A OL β) Z i. Where, Z in is the input impedance ...
