    摘要: A first electrical path has a terminal, and a second electrical path has a terminal. First photovoltaic (PV) dies are electrically connected within the first electrical path. Each first PV die is adapted to convert light having a first wavelength range to electrical energy. Second PV dies are electrically connected within the second electrical path. Each second PV die is adapted to convert light having a second wavelength range different than the first wavelength range to electrical energy. A circuit is electrically connected between the terminals of the first and the second electrical paths to limit an absolute voltage difference between the terminals to no greater than a threshold voltage.

    摘要: In one embodiment, a drive waveform generator to control ejection of liquid from a set of ejection elements in single-pass printing. A first waveform source defines a first aspect of a drive waveform for the set of ejection elements and for other ejection elements. A second waveform source defines a second aspect of the drive waveform for the set of ejection elements but not for the other ejection elements. A circuit uses the first waveform source and the second waveform source to generate the drive waveform having the first and second aspects.

    摘要: A die for a thermal drop-on-demand fluid-ejection device includes thermal firing resistors, low-side switches, and high-side switches. The thermal firing resistors are organized over resistor groups such that each thermal firing resistor is located within only one of the resistor groups. The resistor groups are lesser in number than the thermal firing resistors. Each thermal firing resistor has a first end and a second end. The low-side switches are equal in number to the thermal firing resistors. Each low-side switch connects the second end of a corresponding thermal firing resistor to a low voltage. The high-side switches are equal in number to the resistor groups. Each high-side switch connects the first ends of the thermal firing resistors of a corresponding resistor group to power providing a voltage greater than the low voltage.
