Abstract

In one example in accordance with the present disclosure, a fluidic die is described. The fluidic die includes an array of firing subassemblies grouped into zones. Each firing subassembly includes 1) a firing chamber, 2) a fluid actuator disposed, and 3) a sensor plate. The fluidic die also includes a measurement device per zone to determine a state of a selected sensor plate. The fluidic die includes a selector per firing subassembly to couple the selected sensor plate to the measurement device. The fluidic die also includes a transmission path between each selector and its corresponding sensor plate. A first transmission path for a particular sensor plate has physical properties such that a parasitic capacitance along the first transmission path corresponds to a parasitic capacitance for a second transmission path of a second sensor plate in the zone, regardless of a difference in transmission path length.
