Design, modeling, and characterization of embedded electromagnetic band gap (EBG) structure

Abstract

A practical application and design technique for embedded electromagnetic band gap (EBG) is presented. To suppress noise propagation in a mixed-signal system, an EBG patterned power/ground plane can be an acceptable solution. However, difficulties arise when the EBG structure is put in a strip-line-like environment. Solutions to this are tested with both simulation and measurement. The experimental vehicle used to check the procedure is a prototype load-board for a multi-gigahertz analog-to-digital converter (ADC). Simulation results demonstrate that the proposed embedded EBG structure is effective for the desired noise isolation.
