Patents by Inventor Sofia Vatti

Sofia Vatti 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).

  • Patent number: 11632124
    Abstract: A device for processing digital signals is provided. The device comprises a digital signal source and a converter circuit having a current supply. The digital signal source outputs a codeword. The converter circuit receives the codeword from the digital signal source, receives a current at the current supply, and generates an output signal based on the codeword. The current is generated in accordance with the codeword.

  • Patent number: 11196439
    Abstract: The present invention provides a device for processing digital signals. The device comprises a digital signal source configured to output codewords, a converter circuit configured to generate an output signal based on a first codeword received from the digital signal source, and a feed forward circuit configured to generate an output current based on a second codeword received from the digital signal source. The output current generated by the feed forward circuit is connected to a current supply of the converter circuit. The digital signal source is configured to generate the second codeword based on the first codeword in order to compensate for variations of a supply current of the converter circuit.

  • Patent number: 10721110
    Abstract: The disclosure relates to an error-compensated direct digital modulation device, including: a direct digital radio frequency modulator (DDRM), configured to generate a radio frequency (RF) signal based on a modulation of a digital baseband signal; an error estimator configured to determine an error signal resulting from a deviation based on the generated RF signal and a representation of the digital baseband signal; and an error compensator configured to subtract the error signal from the RF signal to provide an error compensated RF signal.
