Latest Patents

Kalata's latest patents include innovative designs for LED print head power supply circuits. One of his patents describes a power supply circuit that features a reference current source connected to a printer system reference voltage. This design provides a second reference voltage for individual integrated circuit chips. The circuit is controlled by an operational amplifier, which ensures that a plurality of output driver FETs are biased by the reference voltage. Each output driver FET delivers current to an associated LED based on a data signal. Additionally, a second group of control FETs is integrated into the feedback loop of the operational amplifier, allowing for adjustments to the second reference voltage based on different programming data signals.

Another patent focuses on a similar power supply circuit for LED print heads. This design utilizes a plurality of field effect transistors, with their gates connected to the chip reference voltage. This configuration allows for the provision of substantially similar current to multiple light-emitting diodes. The current is enabled for each LED based on the presence or absence of a data signal, ensuring consistent performance across the board.
