Dedicated system-level simulation of ΔΣ modulators

A new approach is presented for significantly speeding up system-level simulation of ΔΣ modulators. The method is based on high-level simulation that can be combined with an acceleration algorithm and has been implemented in C. Also, the decimator has been included yielding a complete and fast simulation of the whole converter. This reduces the bottleneck seen in system-level simulation of complete systems, e.g. receiver front-ends. Different topologies are included as well as the effects of most important nonidealities. Experimental results show the effectiveness of the approach
