Gain formula for inverting op amp

Web1.2 Inverting Amplifier Gain Calculator. Calculate the gain through the relationship between the input and output in this amplifier circuit. The gain of an inverting op amp is the ratio of the feedback resistance to the input resistance, that is, the ratio of Vout to Vin, and the formula is Vout/Vin= (-I1xR2) /(I1xR1)=-R2/R1. Webfor the inverting circuit, the equation is however G 0 f B = − f T ( 1 − β), where β = R 1 R 1 + R 2 using your notations. What this means is that for the inverting opamp circuit the worst case is going to be β = 1 / 2, G 0 = − 1, when you'll only get half the bandwidth of the non-inverting circuit!
