Maximizing Cycle Lengths by Architecture Modification

Abstract

In this chapter, we describe deterministic techniques for maximizing the cycle length by changing the architecture (rather than by setting initial conditions and/or input or by adding dither). We modify the conventional MASH DDSM and refer to the new maximum cycle length structure as HK-MASH. First, the modified first-order Error Feedback Modulator (EFM) is described. Then, the modified EFM is utilized in the HK-MASH DDSM. The spectral performance of second, third, and fourth order HK-MASH modulators with small and large accumulator word lengths is studied by simulation.
