• 論文の詳細を見る

• A new current reused quadrature voltage controlled oscillator (QVCO) is proposed and implemented using UMC 0.18μm 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 1.8V supply voltage, the phase noise of the VCO is -117.13dBc/Hz at 1MHz offset frequency from the carrier frequency of 2.18GHz, the core power consumption is 4.14mW, the total power consumption is 6.48mW and tuning range is about 160MHz.
