A 1.8GHz Voltage-Controlled Oscillator using CMOS technology

A Voltage-Controlled Oscillator (VCO) for 1.8GHz application has been designed using a combination of both 0.13um and 0.35um CMOS technology. The VCO has a large tuning range, which is from 1.39GHz to 1.91GHz, using a control voltage from 0 to 3V. The VCO exhibits a low phase-noise at 1.8GHz which i...

Description
Summary:A Voltage-Controlled Oscillator (VCO) for 1.8GHz application has been designed using a combination of both 0.13um and 0.35um CMOS technology. The VCO has a large tuning range, which is from 1.39GHz to 1.91GHz, using a control voltage from 0 to 3V. The VCO exhibits a low phase-noise at 1.8GHz which is around −119.8dBc/Hz at a frequency offset of 1MHz.
