1992	Sigma-delta modulation with leaky integration and constant input abstract Exact descriptions of the behavior of quantization noise for single-loop, multistage (cascade), and multiloop sigma-delta modulators for a variety of input signals have been found during recent years under the assumption of ideal integration. The techniques used to solve the ideal integrator case do not easily extend to the more realistic model of a leaky integrator sigma-delta. In this paper a dynamical system representation for the leaky integrator sigma-delta with a constant input is developed. Several properties of the resulting piecewise monotone and piecewise linear transformation T on the interval Sang Ju Park, Robert M. Gray	IEEE Trans. Inf. Theory	1
1991	Analysis of a sigma delta modulator with a multi-level quantizer and single-bit feedback abstract An exact analysis of the quantization error of the single-loop single-stage sigma-delta modulator with a multilevel quantizer and single-bit feedback is given. It is shown that the output sequence of this system is identical to that of a coder using a multilevel digital-to-analog converter (DAC) in the feedback loop provided that an extra bit is available in the forward quantizer.> Sang Ju Park, Robert M.
