ALEXANDRIA, Va., March 31 -- United States Patent no. 12,592,681, issued on March 31, was assigned to Apple Inc. (Cupertino, Calif.).

"Capacitance multiplier for decoupling capacitor" was invented by Sang Hyun Woo (Austin, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "An integrated circuit may include one or more circuits coupled to capacitance multiplier circuitry. The capacitance multiplier circuitry may include a capacitor, fixed and tunable resistances, and a transconductance circuit. The tunable resistance can be adjusted to control the overall capacitance of the capacitance multiplier circuitry. The transconductance circuit may include a transistor having a drain terminal coupled to a first elec...
