Stability Analysis of Higher-Order Delta-Sigma Modulators for Sinusoidal Inputs

Nonlinear Stability Prediction of Multibit Delta–Sigma Modulators for Sinusoidal Inputs

“…A combined approach of deploying the separate signal, quantization noise gains in [8], and of the quantization noise amplification in [10] is given in [11], where stability has been predicted for a single-sinusoidal input. In [12], the analysis is extended for predicting stability for dualsinusoidal inputs. An in-depth analysis of the approach in [11], [12] with detailed simulation results is given in [13].…”

“…In [12], the analysis is extended for predicting stability for dualsinusoidal inputs. An in-depth analysis of the approach in [11], [12] with detailed simulation results is given in [13]. As the approaches in [11]- [13] are applied to quantify the stability limits of low-pass ∆-Σ modulators, the analysis and results for predicting stability in band-pass ∆-Σ modulators are detailed in [14].…”

“…As the approaches in [11]- [13] are applied to quantify the stability limits of low-pass ∆-Σ modulators, the analysis and results for predicting stability in band-pass ∆-Σ modulators are detailed in [14]. A novel method based on this approach is given in [15]. It quantifies the maximum stability limits in higher-order ∆-Σ modulators for multiple-sinusoidal inputs.…”
