Issues in the Delivery of RF Current Pulses to a Microprocessor

Passive and active filters are reviewed to define technology requirements for maintaining the impedance seen by the microprocessor below 1mOmega (100mV transient excursion on top of a 0.8-V, 120-A bus) in the gigahertz frequency range. The designs of these filters need to be coordinated so that the...

Zusammenfassung:	Passive and active filters are reviewed to define technology requirements for maintaining the impedance seen by the microprocessor below 1mOmega (100mV transient excursion on top of a 0.8-V, 120-A bus) in the gigahertz frequency range. The designs of these filters need to be coordinated so that the active filter does not have to carry the bulk of the real power or a significant amount of reactive power. Parasitic inductances need to be kept below a picohenry and amplifiers need to have bandwidth approaching a gigahertz to keep the loss below 10% of the real power
