Summary:
This paper analyses the behaviour of a class of MEMS pulsed digital oscillators (PDO) using a nonlinear iterative model. Previous work has shown that in these systems the normalised oscillation frequency as a function of normalised natural frequency is similar to the devil’s staircase fractal. It has also been shown for the most basic such oscillator that several limit cycles can coexist. This means that the steady state oscillation frequency cannot always be uniquely determined by the system parameters, without knowing the initial conditions as well. This effect is explored in greater detail in this paper, and the investigation is widened to include a broader class of PDO topologies.
