中文摘要	A 2 GHz differentially tuned CMOS monolithic LC-VCO is designed and fabricated in a 0.18 mu m CMOS process. The VCO has a 16.15% tuning range (from 1.8998 to 2.2335 GHz) through a combination of analog and digital tuning techniques (4-bit binary switch-capacitor array). The measured phase noise is -118.17 dBc/Hz at a 1 MHz offset from a 2.158 GHz carrier. With the presented improved switch, the phase noise varies no more than 3 dB at different digital control bits. The phase noise changes only by about 2 dB in the tuning range because of the pn-junctions as the varactors. The VCO draws a current of about 2.1 mA from a 1.8 V power supply and works normally with a 1.5 V power supply.
