Abstract :
This paper presents an analysis of the high frequency disturbances from switching operation in a SoC (System on Chip) Buck converter for EMC (Electromagnetic Compatibility) performance improvement. The impact of key design parameters is handled with an analytic approach, allowing Conducted Emission (CE) spectrum prediction.
