Cet article présente un oscillateur commandé en tension (CR-VCO) à courant différentiel de 7 GHz avec une faible consommation d'énergie et un faible bruit de phase utilisant la technologie CMOS de 0.18 µm. La puissance de sortie de ce CR-VCO est améliorée grâce à l'utilisation d'une technique de rétroaction de transformateur trifilaire. Le bruit de phase plus faible est obtenu grâce aux oscillations de tension plus symétriques résultant de l'équilibre amélioré du courant de commutation. Avec une tension d'alimentation de 1.5 V CC, la dissipation de puissance n'est que de 3.4 mW. La plage d'accord totale est de 1.4 GHz (17.9 %) car la tension d'accord va de 0 V à 1.8 V. Le bruit de phase optimal est d'environ -117.3 dBc/Hz à un décalage de fréquence de 1 MHz par rapport à la fréquence centrale de 7.07 GHz. La puissance de sortie correspondante est d'environ -6.8 dBm. Pour le CR-VCO proposé, les facteurs de mérite calculés, FOM et FOMT , sont respectivement de -188.9 et -193.9 dBc/Hz.

Abstract: This paper presents a 7 GHz differential current-reused voltage-controlled oscillator (CR-VCO) with low power consumption and low phase noise using 0.18-µm CMOS technology. The output power of this CR-VCO is enhanced by utilizing a trifilar-transformer-feedback technique. The lower phase noise is achieved by the more symmetric voltage swings resulting from the improved balance of switching current. At a 1.5-V DC supply voltage, the power dissipation is only 3.4 mW. The total tuning range is 1.4 GHz (17.9%) as the tuning voltage ranges from 0 V to 1.8 V. The optimum phase noise is around -117.3 dBc/Hz at a frequency offset of 1 MHz from the center frequency of 7.07 GHz. The corresponding output power is around -6.8 dBm. For the proposed CR-VCO, the calculated figures-of-merit, FOM and FOMT , are -188.9 and -193.9 dBc/Hz, respectively.
