Why is noise suppression important in a power distribution network (PDN)?

0

Noise in a PDN can disrupt the otherwise predictable operation of digital electronics. This may result in data loss or the loss of certain digital functions. In RF receivers, power supply noise can reduce sensitivity or even de-sense the receiver such that it will not be able to receive the intended signal. Power supply noise may also cause undesired modulation of various analog and RF signals. Finally, high frequency noise can radiate from printed circuit boards at levels beyond legal limits for radiated emissions. • Q: What issues impede the adoption of EBG structures in electronic packaging? A: The issue has been one of market perception that EBG structures are too large or the frequency of operation is too high. This perception is understandable given that most if not all of the early publications (2003-2005) on power plane noise suppression where not of practical value to the PCB designer. Many EBG related papers were presented by university researchers and showed early results wh
