Cette lettre présente un nouvel oscillateur commandé en tension en quadrature (QVCO) composé de deux oscillateurs commandés en tension (VCO) Colpitts à n cœurs avec une inductance de queue. Les VCO sont utilisés comme diviseur de fréquence injecté verrouillé par injection (ILFD) asymétrique. La sortie de l'inducteur de queue dans un ILFD est injectée dans le nœud d'injection de l'autre ILFD et vice versa. Le QVCO proposé a été implémenté dans la technologie CMOS 0.18 µm. Avec une tension d'alimentation de 1.0 V, la consommation électrique est de 1.8 mW. La fréquence libre est réglable de 4.68 GHz à 5.03 GHz lorsque la tension d'accord varie de 0.0 V à 1.8 V. Le bruit de phase mesuré est de -113.58 dBc/Hz à un décalage de fréquence de 1 MHz par rapport à la fréquence d'oscillation de 5.03 GHz et le facteur de mérite (FOM) du QVCO est de -185.06 dBc/Hz.

Abstract: This letter presents a new quadrature voltage-controlled oscillator (QVCO) consisting of two n-core Colpitts voltage-controlled oscillators (VCOs) with a tail inductor. The VCOs are used as a single-ended injected injection-locked frequency divider (ILFD). The output of the tail inductor in one ILFD is injected into the injection node in the other ILFD and vice versa. The proposed QVCO has been implemented in the 0.18 µm CMOS technology. At the supply voltage of 1.0 V, the power consumption is 1.8 mW. The free-running frequency is tunable from 4.68 GHz to 5.03 GHz as the tuning voltage is varied from 0.0 V to 1.8 V. The measured phase noise is -113.58 dBc/Hz at the 1 MHz frequency offset from the oscillation frequency of 5.03 GHz and the figure of merit (FOM) of the QVCO is -185.06 dBc/Hz.
