Abstract:
1. A fluid ejection device, comprising: a substrate; a plurality of resistors formed on the substrate; a plurality of switches formed on the substrate, each of the plurality of switches coupled one of the plurality of resistors; a plurality of conductors configured to provide energy to the resistors, wherein each conductor of the plurality of conductors is coupled to a different group of resistors of the plurality of resistors so that each resistor is coupled to only one of the plurality of conductors; a ground conductor coupled to each of the different groups of resistors, so that each resistor of the plurality of resistors is coupled to the ground conductor; a first ground pad coupled to the ground conductor and capable of being coupled with a contact external to the fluid ejection device; and a second ground pad coupled to the ground conductor and capable of being coupled with a contact external to the fluid ejection device, wherein a signal provided on the ground conductor is applied at both of the first ground pad and the second ground pad.
