Analysis of delta-sigma modulators with bandlimited Gaussian inputs

Delta-sigma modulation is gaining widespread use as a monolithic analog-to-digital and digital-to-analog conversion technique in a wide variety of applications. The behavior of delta-sigma modulators depends on the statistics and nature of the input signal. The behavior of the circuit is input-amplitude-dependent, due to the nonlinearity (two-level quantizer). The nonlinear behavior of high-order delta-sigma modulators with bandlimited Gaussian inputs is analyzed
