摘要：An embodiment of this invention relates to an element substrate thatimplements size reduction of the element substrate and simplification of the
arrangement as well as a highly-reliable print operation, a printhead using the same, anda printing apparatus including the printhead. In the element substrate according to thisembodiment, the slope of a ramp wave is changed to generate a plurality of pulses usingone reference voltage. The slope of the ramp wave can be changed by changing themirror ratio or the capacitance of a comparator as well as by changing the resistance of aDAC.
