INK JET PRINTHEAD WITH BALANCED ENERGY SUPPLY AT RESISTIVE ELEMENTS BY ADAPTED FET-CIRCUITS

摘要

An ink jet printhead (11, 12, 13) having FET drive circuits (85) that are configured to compensate for power trace (86, 181) parasitic resistances. The FEt drive circuits have drain regions of selected length in order to set an on-resistance of the FET drive circuits. In another embodiment the size of the FET circuits is selected.
