Case study on the differences between EMI resilience of analog ICs against continuous wave, modulated and transient disturbances

Transient disturbance signals are getting more and more attention lately (e.g. in the automotive industry). Electromagnetic compatibility (EMC) at IC level so far focused on continuous wave (CW) disturbances and how to deal with them, but transient phenomena were not thoroughly studied yet. In this exploratory paper, we perform a case study (based on a basic current mirror) in order to reveal the effects of transient disturbances (as compared to CW ones) and to determine what IC design techniques could be used to deal with them.
