MATLAB/SIMULINK-based high-level synthesis of discrete-time and continuous-time ΣΔ modulators

Abstract

This paper describes a tool that combines an accurate SIMULINK-based time-domain behavioural simulator with a statistical optimizer for the automated high-level synthesis of /spl Sigma//spl Delta/ modulators (/spl Sigma//spl Delta/Ms). The combination of high accuracy, short CPU time and interoperability of different circuit models together with the efficiency of the optimization engine makes the proposed tool an advantageous alternative for /spl Sigma//spl Delta/M synthesis. The implementation on the well-known MATLAB/SIMULINK platform brings numerous advantages in terms of data manipulation, flexibility and simulation with other electronic subsystems. Moreover, this is the first tool dealing with the synthesis of /spl Sigma//spl Delta/Ms using both discrete-time (DT) and continuous-time (CT) circuit techniques.
