Power distribution system for integrated circuits

Abstract

Power distribution system for integrated circuits includes methods to damp resonance between a bypass capacitor network and a power / ground cavity of the printed circuit board that (a) does not require excessive quantities of bypass / damping components or (b) does not require high plane cavity capacitance or in the alternative can insure a Q of less than 1.4 at the transition from the bypass network to the plane cavity impedance cross-over.

Description

technical field [0001] The present invention relates to power distribution for integrated circuits (ICs). More specifically, the present invention relates to power distribution for ICs connected to printed circuit boards (PCBs). Background technique [0002] In recent years, high-speed operating circuit devices have been required, and research has been conducted on them. A circuit device capable of high-speed operation will realize a drastic reduction in processing time that previously took a long time, allow processing previously thought to be impossible, and will make it possible to perform a large number of tasks using one device instead of a plurality of devices, thereby reducing Small processing costs and contribute to the development of services, facilities, functions, etc. [0003] The supply voltage to a circuit should not vary substantially over time. Even if the current consumption of the circuit does not fluctuate substantially over a short period of time, the ...

Problems solved by technology

[0013] 1. Fine interval filter zero;

[0014] 2. High loss dielectric;

[0015] 3. High skin loss interconnection;

Building such a distribution system becomes difficult and expensive, if not impossible, as device performance increases in frequency and power
