摘要： In an embodiment, a method of sensing an ink level includes applying a pre-charge voltage Vp to a sense capacitor to charge the sense capacitor with a charge Q1, sharing Q1 between the sense capacitor and a reference capacitor, causing a reference voltage Vg at the gate of an evaluation transistor, and determining a resistance from drain to source of the evaluation transistor that results from Vg.

摘要： A fluid ejection device includes a plurality of address lines and a fire line for communicating a fire signal. The device also includes a plurality of nozzle circuits coupled to the fire line and the plurality of address lines. Each nozzle circuit is configured, when enabled, to eject fluid via a different one of a plurality of nozzles in response to the fire signal. A subset of the plurality of address lines is coupled to each pair of the plurality of nozzle circuits. Each subset that is coupled to one of the pairs of nozzle circuits is selected so that simultaneous activation of every address line of that subset simultaneously enables each nozzle circuit in the pair or pairs of nozzle circuits coupled to that triad and none of the other nozzle circuits of the plurality of nozzle circuits.
