Abstract
A set of differential equations has been constructed to represent a continuous sigma delta modulator. This paper is concerned with an analysis of these equations, with particular reference to values representing the gains of the feedback loop and the integrator leakage. The results are presented in the form of stability plots. Conditions for the stability of the equations representing second order modulation are derived. The results are used on a conventional simulation of sigma-delta modulation, and the applicability of this method is discussed
