ABSTRACT:
A Σ) analog-to-digital converter (ADC) includes an ADC converter element which receives resonated signals for generating output digital signals, and also a DAC for generating a reconstituted analog signal therefrom. A summer sums the reconstituted and input analog signals with filtered signals to generate resonated signals for the ADC element. A resonator includes a filter receiving the resonated signals, for producing the filtered signals for application to the summer. The summing circuit, the ADC element, and the digital-to-analog converter are in a first feedback loop, and the summer and the filter are in a second loop. The only coupling between the loops is the summing circuit. The delays of the loops become isolated from each other, and the overall performance of the sigma-delta ADC is dependent only on the longer of the two individual delays, rather than on the sum of the delays. This provides wider bandwidth A-D conversion (150).
