In this paper the effect of multi-tone interference on feedback Operational Amplifiers is explored. An analytical model is derived under the assumption of weak non-linearity. It can be used to predict the output offset induced by the superposition of an arbitrary number of sinusoidal disturbance and to evaluate the intermodulation distortion caused by two-tone interference. The proposed model is validated through comparison with computer simulations.

Abstract

In this paper the effect of multi-tone interference on feedback Operational Amplifiers is explored. An analytical model is derived under the assumption of weak non-linearity. It can be used to predict the output offset induced by the superposition of an arbitrary number of sinusoidal disturbance and to evaluate the intermodulation distortion caused by two-tone interference. The proposed model is validated through comparison with computer simulations.
