SUMMARY The spread‐spectrum clock generator (SSCG) is one of the most efficient techniques to reduce the radiated emission of electronic devices. Despite its popularity, there exists no analysis that can be used as the design guidance to accurately project SSCG performance. In this paper, we develop a mathematical model to analyze SSCG EMI reduction and the clock period deviation performance. For model validation, Cadence Spectre simulations are conducted.
