A New Dawn in R&D

The design of power distribution networks in modern highspeed electronic systems has become an ever-growing challenge. From boards with literally no bypass capacitors in the old days, through the one-capacitor-per-pin rule twenty years ago, the power distribution design has reached a state when it is equally as important as the signal-integrity design. The challenges stem from the simultaneous functions that the power distribution network must provide: 1) clean power, 2) return path for high-speed signals, and 3) a resonance free power-distribution network.
