摘要：

Computational cost of transient simulation of SigmaDelta modulators (SigmaDeltaMs) at the electrical level is prohibitively high. Behavioral simulation techniques arise as a promising solution to this problem. This paper demonstrates that both, hardware description languages (HDLs) and commercial HDL simulators, constitute a valuable alternative to traditional special-purpose SigmaDelta behavioral simulators. In this sense, a library of HDL building blocks, modeling a complete set of circuit non-idealities which influence the performance of SigmaDeltaMs, is presented. With these blocks, SigmaDeltaM architectures can be described in two different ways, which are analyzed in detail. Experimental results are provided through several simulations of a fourth-order 2-1-1 cascade multi-bit SigmaDeltaM.
