Abstract
This paper presents a multi-band CMOS VCO using
a double-tuned, current-driven transformer load. The dual fre-
quency range oscillator is based on enabling/disabling the driving
current in the secondary port of the transformer. This approach
eliminates the effect of switches connected directly to the VCO tank
whose capacitance and on-resistance affect both the tuning range
and the phase noise of a typical multi-band oscillator. The rela-
tion between the coupling coefficient of the transformer lo
