Un VCO entièrement intégré utilisant la technique du "turbo-chargeur" pour améliorer les caractéristiques de bruit de phase est présenté. La dégradation du bruit de phase d'une fréquence d'oscillation relativement inférieure dans la plage de réglage était provoquée par une diminution de l'amplitude de l'oscillation due à une capacité totale élevée. D’un autre côté, la dégradation du bruit de phase d’une fréquence relativement plus élevée dans la plage d’accord était causée par un bruit de courant excessif. Un nouveau circuit "turbo-chargeur" augmente le courant de fonctionnement pour obtenir une transconductance suffisante de l'amplificateur lorsque la fréquence d'oscillation est inférieure afin d'améliorer les caractéristiques de bruit de phase. Le bruit de phase du VCO employant cette technique était extrêmement faible et stable, inférieur à -140 dBc/Hz à un décalage de 3 MHz par rapport à la fréquence d'oscillation, dans une large plage de fréquences d'oscillation, d'environ 200 MHz pour une oscillation de 1200 5.8 MHz. Ce VCO fonctionnait avec une consommation de courant de 7.4 à 3 mA à une tension d'alimentation de 0.6 V. Le processus de fabrication était du SiGe BiCMOS de XNUMX µm.

Abstract: Fully integrated VCO using the "turbo-charger" technique to improve phase noise characteristics is presented. The phase noise degradation of relatively lower oscillation frequency in tuning range was caused by oscillation amplitude lowering due to large total capacitance. On the other hand, the phase noise degradation of relatively higher frequency in tuning range was caused by excess current noise. A new "turbo-charger" circuit increased operation current to obtain sufficient transconductance of amplifier when oscillation frequency was lower to improve phase noise characteristics. The phase noise of VCO employing this technique was extremely low and stable, below -140-dBc/Hz at 3-MHz offset from oscillation frequency, in wide oscillation frequency range, approximately 200-MHz for 1200-MHz oscillation. This VCO was operated with 5.8-7.4-mA current consumption at 3-V supply voltage. The manufacturing process was 0.6-µm SiGe BiCMOS.
