Abstract :
Power-distribution networks need to provide flat low impedance over a wide band. Bypass capacitors with different values, and capacitors and planes create resonance peaks, unless the capacitor parameters are selected properly. Distributed matched bypassing is used to create a smooth impedance profile. The ESR of ceramic capacitors is increased by adding embedded annular resistors in series to the capacitors
