## Abstract A new fully integrated, dualβband CMOS voltage controlled oscillator (VCO) is presented. The VCO is composed of two complementary Colpitts VCOs and is implemented in 0.18βΞΌm CMOS technology with 2βV supply voltage. The circuit allows the VCO to operate at two resonant frequencies with a
