TL;DR: In this article, the effect of radiofrequency interference (RFI) in MOS and BJT operational amplifiers (op-amps) is dealt with; in order to obtain analytical expressions which can be useful for design purposes, a second order circuit analysis has been performed.
Abstract: The effect of radiofrequency interference (RFI) in MOS and BJT operational amplifiers (op-amps) is dealt with; in order to obtain analytical expressions which can be useful for design purposes, a second order circuit analysis has been performed. This approach grants a good insight in the nonlinear mechanisms involved in the RFI induced DC offset shift in opamps and relates this behavior to design parameters and parasitics. The validity of the proposed model is discussed comparing theoretical prediction and computer simulation results.

TL;DR: A second-order nonlinear circuit analysis has been performed in order to obtain analytical expressions which can be useful for design purposes, and grants a good insight in the nonlinear mechanisms involved in the RFI induced DC offset shift in operational amplifiers.

In order to obtain analytical expressions which can be useful for design purposes, a second-order nonlinear circuit analysis has been performed. This approach grants a good insight in the nonlinear mechanisms involved in the RFI induced DC offset shift in operational amplifiers and allows us to relate this behavior to design parameters and parasitics. The validity of the proposed model is discussed, comparing theoretical predictions with computer simulations and experimental measurements.
