Abstract
This paper presents an efficient isolation method in mixed-signal systems using a novel electromagnetic bandgap (EBG) structure called the alternating impedance EBG (AI-EBG)for isolating sensitive RF/analog circuits from noisy digital circuits. This EBG structure shows excellent isolation by suppressing almost all possible electromagnetic modes in bandgap frequencies. Measurements on a practical mixed-signal system show the feasibility of using this EBG structure to reduce noise coupling between Rf/analog circuits and digital circuits, especially where a common power supply is used. To the best of our knowledge, this is the first example of a realistic mixed-signal system employing an EBG-based noise suppression scheme.
