摘要：Wireless device portability and power efficiency are the two major challenges in modern device modelling. Voltage ControlledOscillator (VCO) is one the most essential circuit used in wireless systems. From last decade, people want to be connected all thetime using wireless communication devices. In addition, the demand for high bandwidth communication channels has explodedwith the advent of the internet.Thanks to the high density available on integrated circuits, sophisticated digital modulation schemes can be employed tomaximize the capacity of these channels. This has changed the design of wireless and wire line transceivers. We focus on thedesign of a critical sub-block: the voltage controlled oscillator (LC oscillator, VCO). We review the requirements for VCOs andevaluate the advantages and disadvantages of VCO.A new approach is proposed work is aimed to achieve the desired operating frequency, high stability. Power has become one ofthe most important paradigms for microprocessor & ASIC/SOC designs. Hence to have very low power consumption, this paperwork is decided to implement using VLSI technology
