10106071031600 The Distributed SystemModern products require multiple power supply voltages to operate. In most cases, these voltages are generated by multiple switching and linear regulators. The voltages are provided to circuits within the system through a power distribution network (PDN). A PDN includes the printed circuit board (PCB) traces and planes, decoupling capacitors, and in many cases, ferrite beads. These beads are used to help isolate and attenuate high frequency noise signals from particularly sensitive circuits.In high-power devices, such as field-programmable gate arrays (FPGAs) and central processing units (CPUs) which have large and dynamic ope…
