A Wide-band 2-path cross-coupled sigma delta ADC

  title={A Wide-band 2-path cross-coupled sigma delta ADC},
  author={Erkan Bilhan and Franco Maloberti},
  journal={2008 IEEE International Symposium on Circuits and Systems},
The performance of a sigma-delta ADC can be increased by increasing one or more of the main three parameters, over-sampling ratio, the order of the modulators and the number of bits used. Increasing each of these parameters presents a degree of challenge (i.e., the increase in the over-sampling ratio is limited by the technology and the power consumption requirement). This paper presents a new method to obtain 2nd order noise shaping from two 1st order, time interleaved modulators by applying… CONTINUE READING
