Patents by Inventor Victor Manuel da Fonte Dias

Victor Manuel da Fonte Dias has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Analog/digital converter and method for operating an analog/digital converter
    Patent number: 7148834
    Abstract: The invention provides a clocked analog/digital converter for successive approximation which is designed using a jointly used amplifier and a dynamic range expansion facility by means of a special design for the comparison circuit in the first converter stage. The comparison circuits in the analog/digital converter allow decisions to be made for the further signal processing previously in a preceding time period. Two respective generator circuits in successive converter stages share one amplifier. This reduces the amount of space taken up and current drawn, increases the clock rate and simplifies signal processing for signals with high levels.
    Type: Grant
