MEASUREMENTS OF CIRCUIT FUNCTIONS OF ANALOG PARTS OF MIXED-SIGNAL SYSTEMS BY MICROCONTROLLERS

Abstract

In the paper, two approaches to measurements of circuit functions of analog parts of mixed-signal systems controlled by microcontrollers are presented. They base on the utilization of internal resources of the microcontrollers. The first approach uses an analog to digital converter (ADC), an analog comparator and a timer. The second one uses only the ADC and the timer. The measurement procedures are realized also by the microcontroller. As an example, the transfer voltage function of a circuit function was chosen.
