Discussion on Solutions to SSN Based on Ansoft Simulation Analysis

Article Preview

Abstract:

To analyze the inhibition to SSN, we use the design and emulation tools from Ansoft Co., which are used in the optimization design on PDS, integrated with particular circuit designs. Firstly, the traditional means of adding Decoupling Capacitor is adopted to inspect and verify that increased decoupling capacitors will help to increase high frequency response. Secondly, we introduce a high impedance electromagnetic surface texture, which can be applied to decrease SSN. Lastly, we support that EBG is better than traditional adding decoupling capacitor.
