Trevor Clifford Caldwell, Corey Petersen, David Nelson Alldred, Hajime Shibata: Embedded overload protection in delta-sigma analog-to-digital converters. ANALOG DEVICES GLOBAL, Patent Capital Group, March 6, 2018: US09912144

Delta-sigma modulators do not handle overload well, and often become unstable if the input goes beyond the full-scale range of the modulator. To provide overload protection, an improved technique embeds an overload detector in the delta sigma modulator. When an overload condition is detected, coeffi ...
