High-frequency bandpass delta-sigma analog-to-digital conversion

This thesis demonstrates that analog-to-digital (A/D) conversion at the intermediate-frequency stage of a radio is feasible for a wide range of cellular and cordless telephony standards. Placing the A/D converter as close as possible to the front end of the radio has manufacturing advantages and allows the use of sophisticated DSP algorithms which are especially useful with digitally coded transmissions. The type of conversion proposed is a switched-capacitor (switched-C) implementation of a bandpass delta-sigma (BP;An ;Two...
