The model extends the mixed logic dynamical description of freely-running Sigma-Delta (ΣΔ) modulators with single-bit quantizers presented in 1 to the multibit case. Moreover, we use the derived model to compare I-ΣΔs with different loop filter orders and different number of quantizer levels concerning their stability.
