Abstract

A new composite power plane using spiral electromagnetic bandgap (EBG) and external magnetic material is proposed for simultaneous switching noise (SSN) suppression in mixed-signal systems. The proposed power plane has an external magnetic material partially placed on the top of perforated spiral-bridged EBG plane. The EBG bandgap is shifted to lower frequencies by the real part of the permeability (μ_r') and the power plane Q-factor is decreased by the imaginary part of the permeability (μ_r") associated with the magnetic loss. 30 dB suppression of the SSN propagation has been measured from 190 MHz to 1 GHz by virtue of the complex permeability. The proposed EBG power plane is expected to reduce the circuit size and to improve the power integrity of the mixed-signal systems.
