WebIn AFE design, two dynamic element matching (DEM) control modules are applied to current mirrors and bipolar transistors reduce the mismatch greatly and enhance the sensitivity of the temperature sensor. A hybrid ADC that combines ΣΔ ADC and SAR ADC is designed to provide quick conversion results and reduce the power dissipation. WebOct 21, 2004 · Abstract When dynamic element matching (DEM) techniques are applied to generate a precision reference for a (single-bit) sigma-delta modulator, intermodulation occurs between the DEM...
