  • METHODS AND DEVICES FOR ADAPTIVE VOLTAGE STEADYING
    Publication number: 20240356561
    Abstract: A method to drive a digital to analog converter (DAC), the method including setting a reference current for the DAC with a reference current source, a base voltage being responsive to changes in a reference voltage at a reference node coupled with the reference current source; sensing a change in the reference voltage; and adaptively steadying the base voltage based on the change in the reference voltage to maintain proportionality between an output current of the DAC and the reference current.
    Type: Application
    Filed: July 2, 2024
    Publication date: October 24, 2024
    Inventors: Nicola Lupo, Enrico Mammei, Michele Bartolini, Stefano Colli
