| Abstract: | An accurate 1.08GHz CMOS LC voltage-controlled oscillator is implemented in a 0. 35μm standard 2P4M CMOS process. A new convenient method of calculating oscillator period is presented. With this period calculation technique,the frequency tuning curves agree well with the experiment. At a 3.3V supply, the LC-VCO measures a phase noise of -82. 2dBc/Hz at a 10kHz frequency offset while dissipating 3. 1mA current. The chip size is 0. 86mm × 0. 82mm. |
