Linearization method widely used for sigma-delta modulator designing are considering. Modeling linearized sigma-delta modulator and sigma-delta modulator with 1-bit quantizer is carrying out. Modeling results are representing. Quantization error RMS values for linearized model and model with 1-bit quantizer are comparing. Range of application and specificity of linearization method for describing sigma-delta ADC quantization error is given.
