A new current reused quadrature voltage controlled oscillator (QVCO) is proposed and implemented using UMC 0.18 µm CMOS 1P6M process. The proposed circuit topology is made up two low voltage LC-tank VCOs, where the QVCO is obtained using the transformer coupling and current reuse technique. At 1.8 V supply voltage, the phase noise of the VCO is -117.13 dBc/Hz at 1 MHz offset frequency from the carrier frequency of 2.18 GHz, the core power consumption is 4.14 mW, the total power consumption is 6.48 mW and tuning range is about 160 MHz.
