| Abstract: | With the increasing demand for modern digital circuit with fast edge rates and high clock frequencies, simultaneous switching noise has become a major concern. When many active devices switch at the same time, the switching noise generated can cause fluctuations or disturbances in the power distribution system (PDS) which, in turn, leads to a degradation of the signal integrity (SI). When this noise propagates along the waveguide like multi-layer printed circuit boards (PCBs), it will be coupled with other vias to affect the functionality of other circuits. This research work is focus on how to mitigate the noise propagation. The problem of SSN has been discussed intensively over the last decade and different approaches have been taken to mitigate it. Typical used methods include the placement of decoupling capacitors, the use of embedded capacitance, via stitching, or a combination of any of these techniques. The most common drawback of previous methods is the limited frequency bandw... |
