Abstract
In this paper, a novel design method has been proposed to realize feed-forward low-distortion unity STF sigma-delta modulators which are the critical blocks in multi-loop SMASH structure. Using the method, a timing-relaxed stable unity STF 2nd-order modulator has been proposed in detail. After that, an extremely high-resolution SMASH 2(3b)-2(3b)-1(2b) has been suggested using the proposed stages. Extensive results prove the efficiency of this topology.
