Abstract
This paper studies the relationship between nonlinearity and electromagnetic susceptibility (EMS) of integrated circuits (ICs). The research object is a voltage reference circuit with two similar architectures. Experiments results show that direct current (DC) shift appeared on the output in the presence of an electromagnetic disturbance on the ground plane and the small difference in architecture resulted in significant differences in EMS. Since the nonlinearity of the circuit, the “gain” of the circuit is constantly changing in the presence of an electromagnetic disturbance. As a result, asymmetric fluctuations are generated on the output, which means DC shift is generated. Different architectures mean different nonlinearity. It can be concluded that the DC shift generated in the presence of electromagnetic disturbance is the result of the nonlinearity of ICs. The stronger the nonlinearity, the easier it is to generate DC shift. Increasing the linearity of ICs can not only improve the electrical characteristics but also decrease the EMS.
