Abstract

This paper discusses a set of techniques for system-level simulation of continuous-time delta-sigma modulators (CT ΔΣM). In a top-down design flow, system-level simulation is an important part. Done accurately and correctly, system-level simulation can help predict when the circuit operates best and also when and where it fails. The building blocks in a CTΔΣM and how the non-idealities with each building block can be implemented in MATLAB SIMULINK [15] is presented. Simulation results are compared and discussed.
