DESIGN OPTIMIZATION OF A HIGH-ORDER ∑∆-MODULATOR BY THE STABILITY CRITERION
Ashanin Vasily Nikolaevich, Candidate of engineering sciences, professor, head of sub-department of electrical
The article describes a designing method of the ∑ Δ-modulators of high degrees, based on the analytical determination of the modulator feedback coefficients’ values for sustainable operation mode. The authors have calculated coefficients’ value, taking into account the tolerance values and the criterion of minimum standard deviation of the quantization noise. The researcher also provides an example of the ∑ Δ-modulator design of the third degree.
