  • Abstract
    A second-order Delta Sigma modulator is analyzed using linearized gains to model the nonlinearities associated both with the comparator and with the saturation of the integrators. A set of nine equations in nine unknowns is derived for this model. Simulations results are presented that show that saturation of the integrators can actually increase the SNR.<>
