Un nouveau contrôleur de niveau de tension pour les convertisseurs à pompe de charge de faible puissance sera présenté dans cet article. Le contrôleur de niveau de tension proposé réagirait en fonction de la tension pompée dans le convertisseur à commutateur de transfert de charge (CTS). Pour le circuit CTS, l'opération de pompage serait dégradée par l'effet de partage de charge dans le trajet du commutateur auxiliaire. Dans cette étude, un décaleur de tension a été utilisé comme contrôleur de niveau de tension pour surmonter ce problème grave sans consommer trop de surface de puce. Les résultats de la simulation ont montré que le convertisseur peut accepter une entrée nominale de 1.5 V et générer une sortie jusqu'à 8 V sur la base de la technologie CMOS TSMC 0.35 µm. La disposition a consommé une superficie de 125*160 µm2. La sortie la plus élevée obtenue en mesurant la puce réelle était de 5.5 V, ce qui est principalement dû à la limitation que le transistor pouvait tolérer. La charge la plus importante a été estimée à 6 mW, ce qui est suffisamment important pour une application sur puce.

Abstract: A novel voltage level controller for low-power charge pump converters will be presented in this paper. The proposed voltage level controller would react according to the pumped voltage in the charge-transfer-switch (CTS) converter. For the CTS circuit, the pumping operation would be degraded by the charge sharing effect in the auxiliary switch path. In this study, a voltage shifter was used as the voltage level controller to overcome this serious problem without consuming too much chip area. The simulation results showed that the converter can accept a rated input of 1.5 V and generated an output up to 8 V based on the TSMC 0.35-µm CMOS technology. The layout consumed an area of 125*160 µm2. The highest output obtained in measuring the real chip was 5.5 V which is primarily due to the limitation that the transistor could tolerated. The largest load was estimated as high as 6 mW which is large enough for on-chip application.
