The interaction of plane resonances in multi-layer, multiple power-domain board designs is explored for both a production and a test board. We will examine how the parameters of the plane cavities impact noise coupling in consideration of both resonance frequency and Q-value. The effects will be examined in both frequency and time domains for a simple step response. Methods to reduce coupling will also be explored, including thin laminates.
Takeaway
Cavity resonance noise can propagate across multiple power domains. A key indicator to the risk is the Q of the cavity. Thin laminates can lower cavity Q.
Intended Audience
For all audience levels.
