Abstract
This paper proposes a novel two-cap wideband filter that suppresses the high-frequency noise in a power trace routing. By combining electromagnetic bandgap (EBG) theory and decoupling capacitors, the EBG propagation characteristics are studied and a systematic design procedure is proposed. Advanced Design System (ADS) and gigahertz transverse electromagnetic (GTEM) cell measurement are used to validate the accuracy of the proposed analysis and the validity of the design. It is found that the filter gives a 67% stopband with 20-dB suppression, using only two capacitors that are spaced one-twentieth of a wavelength apart. ? 2011-2012 IEEE.
