摘要 The design of a 1.76-2.56 GHz CMOS voltage-controlled oscillator(VCO) with switched capacitor array and switched inductor array is presented.Fabricated in 0.18μm 1P6M CMOS technology,the VCO achieves a 37% frequency tuning range.The measured phase noise varies between -118.5 dBc/Hz and -122.8 dBc/Hz at 1 MHz offset across the tuning range.Power consumption is about 14.4 mW with a 1.8 V supply.Based on a reconfigurable LC tank with switched capacitor array and switched inductor array,the tuning range is analyzed and derived in terms of design parameters,yielding useful equations to guide the circuit design.
