- Abstract:
- This paper presents a method of the measurement of resistance that can be used in a simple microcontroller systems. A direct analog-to-digital conversion (without the measurement of any additional values like a voltage or current) was based on the charge balancing scheme. The whole measurement is divided into two stages. The final result is achieved by computing the difference between them. It makes it possible to eliminate theoretically influences of many factors evoking errors such as long time instability and accuracy of a voltage reference source, influences of supply voltage or offset voltages of a comparator or integrator etc.
