摘要：

In this paper ZSIM, a nonlinear Z-domain SIMulator for sampled data systems, is presented and verified. ZSIM integrates analytic tools, a difference equation simulator, a novel table-based nonlinear Z-domain simulator, and digital signal processing into a workstation environment to provide fast and accurate simulation of delta-sigma modulators. The use of table-based simulation enables simulation of circuit nonidealities including clock feedthrough and saturation. Benchmark comparisons of difference equation simulations and table-based simulations are presented for delta-sigma modulators suitable for use in voice-band coders. © 1990 IEEE
