Investigated of identification circuit with fuse sensors in consumer inkjet printhead chip

摘要

This paper describes the work aimed to develop a thermal inkjet printhead with identification circuit. Identification integrated circuit is a fuse in series with the drain of MOS, after waiting for the wafer factory burn break fuse line. When VID is greater than 3.6V, namely its fuse is blown. It can conclude that its fuse blown point voltage is equal to 3.6V. Curve VGS equal to 15.5V blown fuse parameter analysis can be done.
