Abstract

A principle of designing realizable precision interfaces between sensors and digital ports of microcontrollers and microconverters which enable one not only to measure a physical variable but also to estimate its derivative was proposed. These analog-to-digital interfaces were shown to feature higher precision of conversion without additional precision reference power supplies. The basic requirements on the active analog elements are in good agreement with the “system on chip” VLSI circuit technology.
