This paper illustrates how an adaptive iterative method may be used to verify large signal input stability of a third-order sigma delta modulator across a range of DC inputs, once the initial design parameters the system have been determined using small signal nonlinear stability analysis. This approach is potentially useful to design and optimise stored sigma delta sequences to the modulus controller for a fractional-N synthesiser.
