Description

SIMSAR is a Matlab® Simulink® based toolbox for the study, analysis and design of SAR ADCs developed by Gerardo Salgado.  It includes a fully functional differential SAR ADC Simulink® model, which uses high-level models for the capacitor array, sampling network, comparator, switches, SAR-logic, etc. Circuit imperfections such as capacitor mismatch, sampling noise, sampling non-linearity, finite settling time, comparator noise/offset, among others, are mathematically modeled in order to provide simulation results with an equivalent precision to conventional electrical simulators. As a result, SIMSAR is several orders of magnitude faster than conventional electrical simulators, while keeping a high accuracy. Additionally, a user friendly graphical user interface is also included to facilitate SAR ADC design/study by means of parametric analysis and performance metrics, SNR, INL/DNL. SIMSAR works from Matlab® 2016b and requires Stateflow® license, in both Microsoft Windows and Linux.
