Abstract
Experimental measurements on many different commercial operational amplifiers indicate that a sizable d.c. offset voltage occurs which is a function of input signal amplitude and frequency. This offset is shown to be the result of nonlinear distortion in the input stage. A simple nonlinear model is used to analyze the effect, and calculated and experimental results are in good agreement.
