Phase-Locking Dynamics for Electronic Relaxation Oscillators via Threshold Pulse-Modulation: Comparing Experimental and Analytical Arnold Tongues
Public DepositedWe present detailed analytical and experimental results for a system of two comparator-based relaxation oscillators that are coupled via threshold modulation. Starting with the op-amp circuit equations, we derive parameter conditions that lead to n:1 phase-locked solutions, thereby obtaining predictions for the shapes of Arnold tongues for this system. These tongues are compared to experimental data and good agreement is found. We follow up with a stability analysis of phase-locked solutions. Specifically, we use two-timescale asymptotic analysis, and we check some results obtained therein against experimentally captured dynamics.
