Frequency Stability Analysis of 9-stage Ring Oscillator in CMOS 45nm Technology using Cadence Tool
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 11
Abstract
This proposed paper focuses on design and analysis of a nine stage Ring Oscillator in terms of frequency stability. For a ring oscillator, accuracy is very important. A 9-stage ring oscillator is designed and simulated using 45nm CMOS process technology. The input control voltage is varied from 0.5V to 1V to examine the frequency stability and power consumption of the circuit. The measured output frequency is 2.384 GHz and output power of 0.223µW. Index Terms: CMOS, Oscillator, frequency stability, Cadence Tool
