A fully integrated voltage-controlled oscillator (VCO) in SMIC 0.18-μm 1P6M CMOS technology is presented in this paper. The linear tuning range of VCO is from 2.36GHz to 2.52 GHz. The post simulation results show that the phase noise of the proposed VCO is -118.4 dBc/Hz at 1 MHz offset from the carrier at 2.44 GHz, it meets the requirements for Bluetooth application standard, and the current dissipation of the VCO is 3 mA from the 1.8 V power supply.
