Abstract:
In a continuous-time sigma-delta modulator, by using dynamic element matching (DEM) with respect to comparators of a quantizer, or by generating a plurality of candidate DEM results in advance for selecting an approximate DEM result, a time slot for DEM operations in each cycle of a sampling signal is significantly increased without being rushed.
