ALEXANDRIA, Va., June 17 -- United States Patent no. 12,314,073, issued on May 27, was assigned to PSEMI Corp. (San Diego).
"Low voltage cascode current mirror" was invented by Buddhika Abesingha (San Diego).
According to the abstract* released by the U.S. Patent & Trademark Office: "Methods and devices for a cascode current mirror with low headroom voltage are presented. According to one aspect, a gate voltage to a cascode transistor of an input leg of the current mirror is provided by a feedback block that operates from a mirrored current output by an output leg of the current mirror. The feedback block includes a feedback current mirror that outputs a mirrored current for conduction through a self-biasing diode-connected transistor tha...
