Abstract :
In this article, we propose a new design method of DeltaSigma modulators. We propose an optimal design to shape the frequency response of the noise transfer function (NTF). Generalized KYP (Kalman-Yakubovic-Popov) lemma is used to reduce our optimization to a linear matrix inequality. Design examples are illustrated to show effectiveness of our method.
