Abstract :
A split Δ-Σ ADC topology is proposed which provides enhanced noise shaping by cross-coupling the quantisation errors of the two halves of the structure. Unlike the multi-stage noise shaping 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.
