. It is decided entirely by exter-
nal components. And, the differential input voltage goes to zero.
Why does the differential input voltage go to zero? If the Opamp is in the linear
range, its differential input voltage has to be equal to its output divided by the gain. The
negative feedback present in the circuit resists any change in the output. Consider the
situation when a certain voltage is suddenly applied to the input. Then, the differential volt-
age increases suddenly since the Opamp will take a little time to adjust its output. The large
differential voltage causes the Opamp output ...
