Abstract

In present paper, design of differential ring oscillator using replica bias circuit has been presented. Qualitative analysis of jitter and phase noise of differential ring oscillators in the time and frequency domain is presented respectively which shows great results for the design issues of voltage controlled ring oscillator. The effect of the different number of transistors and their symmetrical arrangement to phase noise and jitter is analyzed. Good agreement between qualitative and quantitative measurements is observed using the cadence virtuoso tool, which is exceedingly applicable in ultra high speed Wi-Fi communications.
