You may use one of the following SI prefix after a value: p=pico, n=nano, u=micro, m=milli, k=kilo, M=mega, G=giga Fill in all values except the one you wish to calculate Input voltage - Input voltage to op-amp Output voltage - Output voltage from op-amp The amplifier in which the input signal is applied to the non –inverting terminal so that the output obtained is non-inverted. Return to Top. And the formula to calculate the gain of a non-inverting amplifier is. The formula for a non-inverting amplifier's gain is slightly different than impedance, which is equal to R1. β = R 2 / (R 1 + R 2) β = 1/A CL. The output voltage is applied across the series combination of R1 and Rf therefore, Vout = voltage across R1 + voltage across Rf, . We have.
