| Abstract: | A fully integrated low phase noise LC voltage controlled oscillator （VCO） is presented in the article. The circuit has a central frequency of 5.25 GHz with a 1.8V supply voltage; working by the 802. lla WLAN standard and implemented in 0. 18 μm CMOS technology. The simulation results show that the oscillator has a phase noise of -121dBc/Hz at 1MHz offset frequency, the tuning range is 31%, the peak-peak output amplitude is 830 mV, and has a good linear purity. |
