摘要： 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.

摘要： System for generating a pulsed signal of the ultra wideband type, comprising a device for direct digital frequency synthesis (DDS) comprising a phase accumulator (ACCP) able to deliver at a first frequency (Fclk) phases coded on i bits and spaced apart by a phase increment (Δp) differing by a power of two and situated in the vicinity of 2i-1, processing means (MT) able to receive said phases and arranged so as to deliver an amplitude-modulated output signal (SG) whose envelope exhibits a succession of regions respectively delimited by zones of zero amplitude (ZA, ZB), each amplitude-modulated signal part situated in one of said regions forming a pulse of the ultra wideband type (IMP) whose central frequency is equal to said first frequency and whose width depends on the value of the phase increment, and control means (MC) able to regulate the operation of the digital synthesis device so as to selectively deliver one or more pulses of the ultra wideband type.
