Abstract
An integrated circuit to drive a plurality of fluid actuators is disclosed. The integrated circuit analog delay circuits coupled in series and to a fire input to receive a fire signal in succession. Each analog delay circuit receives the fire signal and, after a delay, provides the fire signal via an output to a corresponding fluid actuator. A bias circuit is coupled to each of the of analog delay circuits. The bias circuit provides a bias signal to control the delay.
