Assuming ideal op-amp and Rf≫ R current can be modelled as voltage source
I+ = current at positive non-inverting terminal
I- = current at the negative inverting terminal
Vo+ = output voltage due to non-inverting current flow
Vo- = output voltage due to non-inverting current flow
(Taking inverting node ground)
= I+R + I+Rf
Vo− = I−R(−Rf/R)
V0 (offset) = V0+ + V0− (By superposition theorem)
= I+R + I+Rf − I−Rf
= I+R + Rf(l+ − I−)
8mV = 15 × 0.5 × 10−16 + Rf(15 − 10) × 10−9
(8×10−3−7.5×10−6)/5×10−9 = Rf
Rf ≈ 1.6 M Ω
