METHOD OF DECREASE IN THE TEMPERATURE ERROR OF DIGITAL-TO-ANALOG CONVERTERS OF "SYSTEMS ON THE CRYSTAL"
Investigated additive and multiplicative components of additional temperature error converting the main components of information-measuring systems based on "systems on a chip", intended for the treatment of slowly varying signals. It is found that the largest contribution to the additional temperature error of making analog blocks embedded microcontrollers, namely, analog-to-digital and digital-to- analog converters. A method is proposed to reduce the additive and multiplicative error components conversion digital-to-analog converters, wherein the introduction of the feedback from the output of digital-to-analog converter to the input of an analog-to-digital converter of the same microcontroller. We propose an algorithm of the control of the microcontroller information measurement system using the proposed method. The experiment, confirming the effectiveness of the proposed method.
