This equation shows how the reference voltage VREF offsets the input voltage, ... So with an input voltage of 1.25 to 6.26V, a non-inverting amplifier set for a gain of +2 and VREF=2.5V will produce ...

The closed-loop gain and loop-gain equations with the added parallel resistor follow: EQUATION 2. and. EQUATION 3. You lose the pure integration with the addition of R F. The circuit is an amplifier ...

It is by no means a good op-amp by the standards on any era but 1964, as does not have a very high gain, has no short-circuit protection, and requires an external capacitor for frequency compensation.

Put simply, the Miller effect — found in 1919 by [John Milton Miller] — is the change in input impedance of an inverting amplifier due to the gain’s effect on the parasitic capacitance ...
