L'article présente l'analyse, la conception et les performances de VCO différentiels à couplage croisé basés sur PCB (Printed Circuit Board) à l'aide d'un nouveau réservoir LC. Par rapport au réservoir LC classique, un nouveau réservoir LC est composé uniquement d'inducteurs à puce et présente donc l'avantage de fournir une fréquence de coupure plus élevée. Cette caractéristique est attribuée à l'utilisation d'éléments parasites des inductances et condensateurs des puces. Les fréquences de coupure ont été comparées pour les deux réservoirs LC par calcul, simulation et mesure. Ensuite, les oscillateurs différentiels à couplage croisé traditionnels dotés des deux réservoirs LC ont été conçus, fabriqués et réalisés en utilisant des HBT SiGe de 0.35 µm et des puces de type 1005. L'oscillateur mis en œuvre utilisant un nouveau réservoir LC a montré une fréquence d'oscillation plus élevée de 0.12 GHz, tandis que les caractéristiques de bruit de phase étaient presque les mêmes. De plus, l'oscillateur différentiel à couplage croisé utilise un circuit RL série afin de supprimer les oscillations concurrentes. Le VCO différentiel à couplage croisé implémenté utilisant des diodes varactor Si avec un rapport de capacité de 2.5 à 1 a atteint une fréquence d'accord de 0.92 à 1.28 GHz, une puissance de sortie supérieure à -13.5 dBm, une puissance consommée inférieure à 8.7 mW et un bruit de phase. à 100 kHz décalé dans une plage de -104 à -100 dBc/Hz.

Abstract: The paper presents the analysis, design and performance of PCB (Printed Circuit Board)-based cross-coupled differential VCOs using a novel LC-tank. As compared with the conventional LC-tank, a novel LC-tank is comprised of only chip inductors and thus has an advantage in providing a higher cutoff frequency. This feature attributes to the use of the parasitic elements of the chip inductors and capacitors. The cutoff frequencies were compared for both LC-tanks by calculation, simulation and measurement. Then the traditional cross-coupled differential oscillators having both LC-tanks were designed, fabricated and performed by using 0.35µm SiGe HBTs and 1005-type chip devices. The implemented oscillator using a novel LC-tank has shown a 0.12GHz higher oscillation frequency, while phase noise characteristics were almost the same. In addition, the cross-coupled differential oscillator utilizes a series RL circuit in order to suppress the concurrent oscillations. The implemented cross-coupled differential VCO employing Si varactor diodes with a capacitance ratio of 2.5 to 1 has achieved a tuning frequency of 0.92 to 1.28GHz, an output power greater than -13.5dBm, a consumed power less than 8.7mW and a phase noise at 100kHz offset in a range from -104 to -100dBc/Hz.
