This Ph.D dissertation presents a radio-frequency transmitter, made of a direct digital frequency synthesizer, built around a sigma delta and a phase interpolator, and an injection locked oscillator. The direct digital synthesizer generates frequencies between 400 and 500 MHz with a frequency resolution better than 60 Hz. On the other hand, the injection locked oscillator up-converts synthesizer output up to the Bluetooth band by multiplying frequencies by 5. Moreover, the locked oscillator filters injected signal phase noise up to recover the one of the free running oscillator. The locked oscillator bandwidth can be tuned digitally. This transmitter has been developed on 65-nm CMOS technology.Cette thèse présente un émetteur radio-fréquenc...
