Abstract
A fluidic die may include a number of actuators. The number of actuators form a number of primitives. The fluidic die may include a digital-to-analog converter (DAC) to drive a number of the delay circuits. The delay circuits delay a number of activation pulses that activate the actuators associated with the primitives to reduce peak power demands of the fluidic die. A number of delay circuits may be coupled to each primitive.
Claims20
A print circuit comprising:
- at least one delay circuit having a connection for coupling with a respective primitive of a fluid ejection die, the primitive comprising a number of fluid ejection actuators of the fluid ejection die;
- a digital-to-analog converter (DAC) to drive the at least one delay circuit, the at least one delay circuit configured to delay a number of activation pulses that activate the fluid ejection actuators of the respective primitive to reduce peak power demands of the fluid ejection die;
- and
- a DAC input to receive an input voltage to be provided to the DAC wherein the DAC is tuned by the input voltage.
1 more element
A print circuit comprising:
- at least one delay circuit to be coupled to at least one respective primitive, the primitive associated with multiple fluid ejection actuators of a fluid ejection die;
- a digital-to-analog converter (DAC) to drive the at least one delay circuit, the at least one delay circuit delaying at least one activation pulse, wherein the DAC receives a bias voltage and the bias voltage is tunable to adjust a delay of the at least one delay circuit.
A print circuit comprising:
- a digital-to-analog converter (DAC) to drive at least one tunable analog delay circuit, the at least one tunable analog delay circuit coupled to at least one primitive on a fluid ejection die, the at least one primitive comprising multiple fluid ejectors, wherein a bias voltage provided to the DAC modifies a delay produced by the delay circuit.
