This paper presents a 0.13/spl mu/m CMOS 1.7GHz VCO with frequency divider, suitable for ultra-low-power hearing-aid applications. The circuit has a 16% tuning range, a minimum power consumption of 320/spl mu/W from a 0.8V power supply, power-supply and temperature compensation, an excellent 188dBc/Hz figure-of-merit without the need of off-chip components, and an area of 0.2mm/sup 2/.
