| Abstract(in English) | It is well known that high-order delta-sigma modulators become unstable due to the nonlinearity of the quantizer. In this paper, we study the operation of the modulators based on modeling the nonlinear quantizer with a linearized gain, and propose the criterion for the stability of the modulators. Input signal amplitude dependencies of modulator's stability and signal-to-noise ratio are analyzed. Finally, some examples are demonstrated, which shows the good agreement with the theory. |
