Patents by Inventor Laurent Camino

Laurent Camino 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).

  • Digital to digital Sigma-Delta modulator and digital frequency synthesizer incorporating the same
    Patent number: 6822593
    Abstract: A digital to digital Sigma-Delta modulator comprises an input which receives a digital input value encoded over N bits, an output which delivers a digital output value encoded over n bits, where n is less than N, and at least a first Sigma-Delta cell which includes a quantizer having a quantization interval which is a prime number. The choice of a prime number decreases the power of the limit cycles (lines with a power value higher than the local mean value) which may appear depending on the input code of the modulator and on the initial conditions. Application is proposed to a digital frequency synthesizer.
    Type: Grant
