ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,451,899, issued on Oct. 21.
"Digital DC-DC controller" was invented by Chenjun Hsu (Miaoli County, Taiwan).
According to the abstract* released by the U.S. Patent & Trademark Office: "The present application provides an all-digital multi-phase DC-DC controller. The digital DC-DC controller includes time-based analog-to-digital converters (ADCs) for converting analog voltage signals into digital-domain signals so as to benefit from gate length scaling without limited by the low voltage swing. Also, the DC-DC controller further includes a digital control circuit and a time-based modulator. The digital control circuit can control the time-based modulator in a digital domain, thereby red...
