Integrating Grounded Resonators with Slot-crossing Differential Signals to Suppress Common-mode Radiation

Abstract

A novel grounded resonator technique is proposed and both of its mechanism and performance is demonstrated. The proposed method can greatly suppress the electromagnetic radiation caused by the common-mode noise of slot-crossing differential line at GHz frequency range. Apart from the predominant solution of using stitching capacitors, this technique can be fabricated under standard PCB process and is effective for frequency of noise source above gigahertz.
