In this chapter, the effect of EMI injection in output nodes of analog circuits is studied. A general framework is developed, categorizing the EMI behavior of output structures into two major families, namely output circuits of the common-drain type and those of the common-source type. It is shown mathematically that output circuits of the common-source type are much more immune to EMI compared to their common-drain counterparts. These observations are applied in three designs, namely an externally trimmed DC current reference circuit with high EMI immunity, and two integrated EMI resisting LIN drivers.
