Fast-response hybrid filter for CPU and FPGA power delivery
This technology is a hybrid power supply circuit that combines a traditional switching voltage regulator with a small, efficient linear regulator working in parallel. When a processor or chip suddenly demands a burst of current faster than the switching regulator can respond, the linear regulator instantly fills the gap — but only at that moment, keeping its own heat generation low. A key insight is that by mathematically matching the impedances of both regulators, the bulky filtering capacitors normally required can be dramatically reduced or replaced by tiny on-chip capacitors. The result is a smaller, more responsive power delivery system suited for modern high-speed processors.
What you could build
A compact, high-efficiency power module for server CPUs, FPGAs, and high-performance ASICs that delivers faster voltage response with fewer bulky capacitors; the primary buyers would be semiconductor companies and server/data center hardware OEMs seeking to shrink power delivery footprints.
Who in Virginia should care
Northern Virginia data center operators and defense electronics firms (e.g., those supplying high-performance computing hardware to government agencies) would have direct interest in compact, high-slew-rate power delivery.
Readiness: Prototype likely
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
