  5. 19. Analysis, Estimation and Compensation of Mismatch Effects in A/D Converters

    Författare :Jonas Elbornsson; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; A D converter;

    Sammanfattning : The trend in modern communication systems is to replace as much analog circuits as possible with digital ones, to decrease size, energy consumption and cost. An analog to digital converter (ADC) is the interface between the analog and digital parts. Replacing analog parts, such as mixers, with digital ones requires higher sampling rates. LÄS MER
