Optimum design of power distribution system via clock modulation

This paper presents a method for extracting current excitations, which a microprocessor (/spl mu/P) can present to its power distribution system (PDS) as a function of frequency. The method uses a clock modulation technique to measure the impedance seen by the uP.

A low-loss millimeter wave passive frequency band splitting technique

This paper presents a millimeter wave-guiding technique for passive frequency band splitting and combining. The devices which can be made possible as a result of implementing this technique have potential for use in high speed signaling systems for the purpose of facilitating the transmission of multiple carrier frequency signals through the same guiding structure. The device splitting operation causes minor signal attenuation or power loss in the split frequency bands and is based upon modal waveguide design principles.
