  • Electronic circuit comprising a device to measure phase noise of an oscillating and/or resonant device
    Patent number: 8154307
    Abstract: An electronic circuit includes several (at least two) oscillating and/or resonant devices. The circuit uses a measuring device to measure the phase noise of one of the two oscillating/resonant devices. This measuring device is integrated on a chip on which the oscillating/resonant device to be measured is also integrated. The circuits and methods described find application in the area of radiofrequency/high frequency electronics RF/HF, in particular adapted to general public applications in mobile communication systems and/or to metrology.
