Nonlinear Model-Based Approach for Accurate Stability Prediction of One-Bit Higher-Order Delta–Sigma Modulators

Predicting the stability of Delta-Sigma (Δ-Σ) based analog-to-digital (ADC) and digital-to-analog converters (DAC) is complicated to predict due to the non-linear behavior of the quantizer. A novel non-linear based model approach is employed to develop the single-bit quantizer models that are employed to quantify stability. This circumvents the requirement for lengthy simulations in the design process and enable optimization of the design of higher-order single-loop Δ-Σ ADCs/DACs with increased dynamic ranges for various applications that require multiple sinusoidal and Gaussian signal, such as for orthogonal-frequency division multiplexing (OFDM) in telecommunication applications.
