Abstract:
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.
