Abstract :
Noise-coupled multi-cell delta-sigma ADCs are presented. By providing quantization noise coupling between identical delta-sigma ADCs, one can effectively raise the order of the modulator. Cross-coupled noise injection also provides an efficient way to realize higher-order time-interleaved ADCs.
