"WebThe equivalent circuit for high frequencies will be an inverting op-amp with a finite gain -R 2 /R 1. As a consequence, in the high-frequency regime, when the capacitor impedance tends to zero, the gain will therefore be limited to R 2 /R 1 instead of ∞ which would make the output to saturate as pinpointed in the ideal circuit section.
