A 6-GHz Low-Phase-Noise Voltage-Controlled Oscillator

摘要：

A 6-GHz low-phase-noise voltage-controlled oscillator (VCO) is proposed. A varactor based coarse tuning method which differs from the traditional switchcapacitor based architecture is adopted. The source feedback resistors and a modified filtering technique are used to suppress low and high frequency noises of current source, respectively. To verify the concept, a prototype VCO is fabricated in 0.13μm CMOS technology. The measurement results show that the VCO has a phase noise of -119dBc/Hz at 1MHz offset and a tuning range of 6.1GHz to 6.7GHz. The VCO core draws only 4.7mA current from 1.2V supply voltage.
