摘要: In this letter, a 0.18 mu m CMOS quadrature voltage-controlled oscillator (QVCO) using a simple distributed metal-insulator-metal (MIM) poly-phase network is presented. The MIM network is used to replace the conventional coupling transistors and to lower the power consumption and phase noise. The QVCO has a tuning range from 5.29 to 5.67 GHz and the power consumption is about 5.2 mW at a 0.6 V supply. At 1-MHz offset from a 5.48-GHz carrier, the measured phase noise is -118.58 dBc/Hz.
