1-15. (canceled)
A method for use with a series of analog delay circuits to drive a plurality of fluidic actuators with a fire signal, the method comprising:
- disabling a bias signal to each of the analog delay circuits, the bias signal to affect a selected delay in the analog delay circuits;
- and
- providing the fire signal through the series of analog delay circuits with the bias signal disabled.
A fluid ejection device, comprising:
- a plurality of actuators to eject the fluid;
- a plurality of analog delay circuits coupled in series and coupled to the plurality of actuators;
- fire logic coupled to the plurality of analog delay circuits to provide a fire signal to the plurality of analog delay circuits to drive the plurality of actuators;
- a bias circuit coupled to the plurality of analog delay circuits to provide a bias signal to each of the analog delay, the bias signal to effect delay in each of the analog delay circuits;
- and
- configuration logic circuit coupled to the bias circuit to disable the bias signal.
