This Paper describes the design ofcomplementary Metal Oxide Semiconductor - Voltage Controlled Oscillator (CMOS - VCO). Design which is more and simple area efficient method, since the other methods uses complex architectures of Current Starved VCO’S. Generally VCO’S uses more number of Transistors that occupies Larger Area and consumed more power. This Current Starved VCO introduces huge amount of parasitic effect, which is undesirable but it is also unavoidable. Their effect can be minimized by using CMOS Based Ring Oscillator VCO. This is because of the usage of less number of transistors in Ring Oscillator VCO. This Paper involves the designing of VCO using Ring Oscillators. At first, the Inverters are designed. Then, these inverters are replicated to form Ring Oscillator. The Ring Oscillators in this Paper uses Three Stage Inverters. Ring Oscillator VCO consumes less area and less power since they use less number of Transistors compared to Current Starved VCO. Design and Performance Analysis of VCO is done in cadence schematic editor using Cadence Virtuoso 180 nm technology. This approach results in the reduction of Area by minimizing transistors in an operating Frequency of 3.42 GHz with the Power supply of 1.2 Volt. This report includes the results that are obtained during circuit simulation.
