New closed-form equations are proposed for frequency and amplitude of a ring oscillator. The method is general enough to be used for all types of delay stages. Using exact large-signal circuit analysis, closed-form equations for estimating the frequency and amplitude of a ring oscillator are derived as an example. The method takes into account the effect of… (More)
