Frequency Analysis of Ring Oscillator at Different Technology Node

This paper deals with the design and analysis of the frequency of ring oscillators using the CMOS 45nm, 32nm, 22nm in a Symica simulation tool. A Ring Oscillator is an effective device made up of an odd number of NOT gates and its output runs between two levels of power standing up and down. There are many challenges ahead while designing a CMOS ring oscillator that can be delay, sound, and glitches. CMOS is the technology of choice for several applications, low-power CMOS oscillators are in high demand. The frequency of a CMOS ring oscillator was measured using waveform time zones for five, seven, and nine phases. This aids in the comparison of ring oscillators at various technology nodes and it is observed that the frequency is found to be maximum at a five-stage ring oscillator in each case i.e. 12.97GHz at 45 nm, 8.25GHz at 32 nm, 4.74GHz at 22 nm.
