ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,451,805, issued on Oct. 21, was assigned to GlobalFoundries U.S. Inc. (Malta, N.Y.).
"Feedback current depended ramp generator for switched mode power supply" was invented by Matthias Hoffmann (Dresden, Germany).
According to the abstract* released by the U.S. Patent & Trademark Office: "To reduce sub-harmonic oscillations in a Switched-Mode Power Supply (SMPS). a ramp generator circuit of the SMPS produces a ramp signal having an amplitude corresponding to a sensed current through an energy storage device, such as an inductor, of the SMPS. The ramp signal is used to control a duty cycle of the SMPS. The ramp generator circuit may include a reference current circuit, a ramp capacitor...
