• A complementary cross-coupled differential Colpitts voltage controlled oscillator (VCO) is reported. The combination of gmboosting and the complementary transistors allows record low power integrated VCO implementation. The proposed VCO and the corresponding parallel quadrature VCO (P-QVCO) are implemented using 0.25-μm CMOS technology for 1.8GHz operation. Measurements for the VCO and P-QVCO show phase noise of -116.8 and -117.7dBc/Hz at 1MHz offset, while dissipating only 0.4 and 1.1mA from a 0.9-V supply, respectively.
