Abstract :
Oscillators used in digital systems experience substantial supply and substrate noise. This paper describes the timing jitter of oscillators in such applications, demonstrating that the contribution of device electronic noise is typically much less significant than that due to environmental noise. We utilize a frequency modulation model to predict the jitter, and study the effect of design parameters such as device dimensions and number of stages
