    摘要: A nozzle firing cell may comprise a firing transistor and a pre-charge transistor having a source and drain coupled between a pre-charge line and a gate of the firing transistor wherein the pre-charge line is routed over the gate of the pre-charge transistor. A fluid ejection device may comprise a circuit comprising a nozzle firing cell, the nozzle firing cell comprising a firing transistor and a pre-charge transistor having a source and drain coupled between a pre-charge Sine and a gate of the firing transistor in which the pre-charge line is routed over the gate of the pre-charge transistor. A circuit may comprise a number of firing transistors and a number of pre-charge transistors each having a source and drain coupled between a pre-charge line and a gate of one of the firing transistors in which the pre-charge line is routed over each of the gates of the pre-charge transistors.

    摘要: In an embodiment, a fluid ejection device includes a fluid feed slot formed in a printhead die and a plurality of printhead-integrated ink level sensors (PILS). A fluid ejection device may include a first PILS to sense an ink level of a first chamber in fluid communication with the fluid feed slot, the first PILS to detect an empty ink level of the first chamber when the fluid ejection device is at a first ink level state, and a second PILS to sense an ink level of a second chamber in fluid communication with the fluid feed slot, the second PILS to detect an empty ink level of the second chamber when the fluid ejection device is at a second ink level state, different than the first ink level state.

    摘要: A fluid ejection device is described. In an example, a device includes a substrate having a chamber formed thereon to contain a fluid. A metal layer includes a resistor under the chamber having a surface thermally coupled to the chamber. At least one layer is deposited on the metal layer. A polysilicon layer is under the metal layer comprising a polysilicon structure under the resistor to change topography of the resistor such that the surface is uneven.
