Abstract :
A split delta-sigma ADC topology is proposed, which provides enhanced noise shaping by cross-coupling the quantization errors of the two halves of the structure. Unlike the multi-stage noise shaping (MASH) architecture, the new structure is insensitive to mismatch errors, and it does not reduce the stability of the loops. Simulations confirm the effectiveness of the proposed scheme.
