ALEXANDRIA, Va., Nov. 25 -- United States Patent no. 12,483,116, issued on Nov. 25, was assigned to Cypress Semiconductor Corp. (San Jose, Calif.).
"Low-power fast-transient current-sink buffer" was invented by Adrian Lin (Austin, Texas).
According to the abstract* released by the U.S. Patent & Trademark Office: "A current-sink buffer is provided including a differential amplifier having a closed first-loop to provide a buffered output voltage, and a closed second-loop to sink transients in a load current of an output to ground. The first-loop includes a first transistor with a gate coupled to a reference-voltage, and a source coupled to a current-source; a second transistor with a gate coupled to a drain and the output, and a source coup...
