Voltage controlled oscillator is widely used in many electronics devices. It is used to generate the signals for broadcast by radio and television transmitters, clock signals that regulate computers and quartz clocks, and the sounds produced by electronic beepers and video games. In this paper we propose a novel way to modify the existing VCO and provide an enhancement to control the output voltage level which can be used in any application of varying required voltage level. The simulation is done using tanner using 250nm dimension.
