Design of 2.4 GHz CMOS LC Tank Voltage Controlled Oscillator (VCO) for PLL using 0.18 µm CMOS Technology

Abstract

This paper presents the design of a 2.4 GHz LC Voltage Controlled Oscillator implemented using 0.18 µm CMOS technology. The LC VCO achieves a simulated phase noise of −97.76 dBc/Hz at 1MHz of offset frequency. The output frequency of VCO can be tuned from 2.4 GHz to 2.48 GHz frequency range which correspond to an 80 MHz tuning range Bluetooth device.
