This paper presents a tunable CMOS voltage controlled oscillator (VCO) used to generate 1.8GHz, 3.6GHz and 4.2GHz frequencies for multistandard mobile receiver. The switch architecture is used to combine three VCO's to get a better phase noise performance tunable VCO. The architecture is able to select the operating frequency based on a control signal. The VCO's are independently designed with the view of switch architecture combination, so the phase noise performance of this architecture is well below the specification of GSM and WCDMA standards.
