Detection and Removal of Limit Cycles in Sigma Delta Modulators


Sigma delta modulation is a popular method for converting signals from analog to digital and vice-versa. However, sigma delta modulators (SDMs) may suffer from limit cycles, where the output bits may enter a repeating pattern. Current methods of preventing this phenomenon introduce unwanted noise, do not always succeed, and are often implemented when not… (More)
