Development of Sigma-T ADC with analogue compensation of error caused by edge effects

Abstract

In this article work on implementation and studies of algorithm of analog compensating of error from edge effects for sigma-T analog-to-digital converter is carried out. The simulation model in a software environment of Matlab/Simulink is created. A row of model experiments is carried out and values of a standard deviation of ADC linear function without compensating and with analog compensating respectively are calculated. The operability of algorithm is assessed and features of its implementation in a software environment are specified.
