ALEXANDRIA, Va., Aug. 20 -- United States Patent no. 12,393,067, issued on Aug. 19, was assigned to LAPIS Technology Co. Ltd. (Yokohama, Japan).
"Driver circuit for suppressing variations in slew rate" was invented by Hijiri Shirasaki (Yokohama, Japan).
According to the abstract* released by the U.S. Patent & Trademark Office: "In a driver circuit, a bias voltage generation circuit generates and outputs a bias voltage for determining a bias current of an output amplifier. A memory stores a trimming code with which a slew rate of an output voltage outputted by the output amplifier is adjusted to fall within a target range set in advance. In an adjustment mode for adjusting the slew rate, a slew rate adjustment circuit adjusts the slew rate...
