Latest Patents
Sam Mahjouri holds a patent for an "Energy control circuit for a thermal ink-jet printhead." This invention focuses on a circuit designed to control the energy delivered to a heater resistor within a thermal ink-jet printhead. The circuit features a decoder that receives an address for the heater resistor in a multiplexed environment. When the heater resistor is addressed, the output of the decoder is level shifted through a pair of inverters and transmitted to the gate of a PMOS driver. This driver delivers the necessary energy to the heater resistor. The PMOS driver adjusts its output voltage based on the voltage level of the adjacent inverter output. Feedback circuitry, in the form of an analog or digital comparator, compares the driver output voltage against a reference voltage. The comparator's output signal is fed back through the level shifter, allowing for precise control of the energy delivered to the heater resistor.
