2. Introduction:
• With the advancement of internet of things voltage controlled oscillator (VCO’s) are most
important building blocks for low power and ultra wide band applications
• Where they are predominantly used as a high frequency clock generating subsystems,
notably in cutting edge wireless systems used for sub 5G band of frequency that either
encompasses the implementation of the VCO with high oscillation frequency and low close-
in phase noise, in PLL and in frequency synthesizer.
• VCO constitute a critical component in many RF transceivers and are commonly associated
with signal processing tasks like frequency selection and signal generation.
• Voltage controlled oscillators play a critical role in communication systems, providing
periodic signals required for timing in digital circuits and frequency translation in radio
frequency Circuits.
• This review paper compares the performance parameters of CMOS Ring oscillators
architecture and current starved Voltage-controlled oscillators on the basis of Power
consumption, Phase-Noise, Tunning range, Technology used and supply voltage.
• Here investigation design of different ring oscillator are utilized to get comparative analysis
for utilization in ultra wide band
