ALEXANDRIA, Va., Dec. 31 -- United States Patent no. 12,510,567, issued on Dec. 30, was assigned to WILL SEMICONDUCTOR (SHANGHAI) Co. LTD. (Shanghai).

"Current sense amplifier" was invented by Hiroyuki Kimura (Miyagi, Japan).

According to the abstract* released by the U.S. Patent & Trademark Office: "A current sense amplifier measures a voltage drop in a drive transistor LS to measure the current flowing through the drive transistor LS. The current sense amplifier includes a preamplifier pre-amp, to which a voltage across the drive transistor LS is inputted, and which obtains a positive output and a negative output corresponding to a voltage difference of the inputted voltage across the drive transistor; and a switch sw, which connects th...
