Abstract
In one example in accordance with the present disclosure, a fluid ejection device is described. The fluid ejection device includes a number of nozzles to eject an amount of fluid. A first field-effect transistor (FET) activates a first fluidic operation component and a second FET activates a second fluidic operation component. The first FET and the second FET are selected from among a high-side switch FET, a low-side switch FET, and a hybrid FET and the first FET and the second FET are different from one another.
Claims15
A fluid ejection device comprising:
- a number of nozzles to eject an amount of fluid;
- a first field-effect transistor (FET) to activate a first fluidic operation component;
- and
- a second FET to activate a second fluidic operation component;
- wherein:
- the FETs are selected from the group consisting of a high-side switch FET, a low-side switch FET, and a hybrid FET;
- and
- the second FET is different from the first FET.
A fluid ejection system comprising:
- a fluid ejection device comprising:
- a number of nozzles to eject fluid through a number of nozzle orifices;
- a number of high-side switch firing field-effect transistors (FETs) to select and activate at least one of the number of nozzles;
- and
- a number of non-high-side switch fluid transport FETs to move fluid through the fluid ejection device;
- and
- a controller to:
- eject fluid through the number of nozzle orifices by activating at least one of the number of high-side switch firing FETs;
- and
- move fluid through the fluid delivery device by activating at least one of the number of non-high-side switch fluid transport FETs.
A fluid ejection device comprising:
- a fluid slot to transport fluid between a fluid reservoir and nozzles that eject the fluid;
- a number of fluid ejection cells fluidly connected to the fluid slot, each fluid ejection cell comprising:
- a nozzle to eject an amount of fluid through a nozzle orifice;
- a firing field-effect transistor (FET) to select and activate an ejector of the nozzle;
- and
- a fluid transport FET to selectively move fluid between the fluid slot and the fluid ejection cell;
- wherein the firing FET and the fluid transport FET are:
- selected from the group consisting of a high-side switch FET, a low-side switch FET, and a hybrid FET;
- and
- different from one another.
