The modern telecommunication services require increasingly wide tuning bands and improved spectral purity in order to support the growing demand for high data rate in the new generation wireless standards. The resulting VCOs have to deal with a difficult trade-off between wide tuning bandwidth and phase-noise. The paper introduces a new VCO architecture with a double tuning control, the former coarse to select the band the latter fine to precisely tune the frequency. The VCO is organized in an innovative distributed arrangement. Experimental results validating the theory are reported and discussed.
