ALEXANDRIA, Va., March 17 -- United States Patent no. 12,578,364, issued on March 17, was assigned to Renesas Electronics Corp. (Tokyo).
"Current sense circuit" was invented by Yoshiaki Ishizeki (Tokyo) and Makoto Tanaka (Tokyo).
According to the abstract* released by the U.S. Patent & Trademark Office: "A current sense circuit is provided. The circuit includes a current mirror circuit QN1, QN2, and diode-connected QP1, QP2, QP3, and QP4 with their bases connected together, stacking such that the diode-connected side (QN1, QP1, QP3) aligns and connecting the emitter of QP2 to the collector of QP4. Furthermore, the gates of MP1 and MP2 are connected to the collector of QN2 and QP2, respectively. Additionally, the source of MP1 is connected...
