Abstract
Fluid injection devices comprise M sets of fluid injection units. Each fluid injection unit comprises N injectors separately connecting to a driver. A controller separately transmits a signal to the driver, thereby simultaneously driving a selected injector of each of the M sets of fluid injection units. A non-selected injector of each of the M sets of fluid injection units does not trigger bipolar junction transistors (BJTs).

A fluid injection device, comprising:
- M sets of fluid injection units, each fluid injection unit comprising N injectors, each injector separately connecting to a driver;
- and
- a controller separately transmitting a signal to the driver, thereby simultaneously driving a selected injector of each of the M sets of fluid injection units;
- wherein a non-selected injector of each of the M sets of fluid injection units does not trigger a bipolar junction transistor (BJT).

A fluid injection device, comprising:
- M sets of fluid injection units, each fluid injection unit comprising N injectors, each injector separately connecting a MOS transistor comprising a drain, a gate, a source, and a base, wherein the drain connects the injector via a signal transmitting circuit, and wherein the junction capacitance between the drain and the base is equal to or less than 1.139×10−14(F/μm2);
- and
- a controller separately transmitting a signal to the driver, thereby simultaneously driving the injector of each of the M sets of fluid injection units;
- wherein the injector is driven by the driver without triggering a bipolar junction transistor (BJT).
