Abstract
The stability of a high-order sigma-delta modulator has been addressed under dc input. A new approach for stability analysis is proposed. A nonlinear circle map is suggested to model the dynamics of the modulator. The stability problem is handled using an analogy between the dynamics of the sigma-delta modulator and the sinusoidal digital phase-locked loop (DPLL). An approximate fixed point solution is presented and stability criteria are derived
