    Abstract
    In this thesis an ultra low voltage differential capacitive feedback VCO is being proposed .The VCO operates at very low supply voltage of 0.6V.The VCO uses techniques like Forward Body Bias (FBB), and capacitive feedback to achieve high performance in terms of phase noise and output voltage swing. It uses differential MOS varactors for frequency tuning due to which all low frequency noise such as flicker noise gets rejected. Inductor was designed and it was simulated in IE3D electromagnetic simulator to achieve good Quality factor. This VCO achieves a very low phase noise of -119dBc/Hz@1-MHz offset frequency, power consumption of 3.27mW, and tuning range of 6% .All the circuit simulations of VCO were simulated in SpectreRF using TSMC 0.18μm CMOS technology
