20.500.12556/DKUM-82238 Interpolacija signalov anizotropnih magnetnih senzorjev v integriranem vezju dajalnika položaja magistrsko delo Interpolation of anisotropic magnetic sensor signals in position encoder asic Magistrsko delo obravnava interpolacijo signalov več tipov AMR senzorjev, ki se v današnji industriji uporabljajo v različnih aplikacijah. Senzorji AMR so brezkontaktne naprave, ki zaznavajo in merijo smer magnetnega polja, kar se lahko uporablja za zaznavanje položaja in vrtenja. V magistrskem delu smo podali princip delovanja AMR senzorjev, primerjavo različnih izvedb AMR senzorjev in primerjalno analizo z drugimi vrstami magnetnih senzorjev. Podajamo razlago in primer številnih vplivov na točnost merjenja v funkcionalnem sistemu (odmik, temperatura, histereza, amplituda, ojačenje itd.). Med drugim nas je zanimala predvsem arhitektura in metodologija načrtovanja interpolatorjev v integriranih vezjih, ki procesirajo senzorske signale. Poudarek je bil na obstoječih zasnovah interpolatorjev ter njihovi primerjavi. Delo se zaključi s študijo primera in zasnovo napetostnih referenc, ki predstavlja enega izmed pomembnejših blokov interpolatorja. Na koncu predstavimo vezje napetostne reference s kompenzacijo višjega reda, ki bo manj občutljivo na procesne variacije. Delo se zaključi z razpravo o nadaljnjem razvoju napetostnih referenc, ter povzetkom celotnega dela. The master's thesis deals with the interpolation of signals of several types of AMR sensors, which are used in today's industry in various applications. AMR sensors are non-contact devices that sense and measure the direction of a magnetic field which can be used to sense position and rotation. In the master's thesis, we also gave the principle of operation of AMR sensors, as well as a comparison of different types of AMR sensors and a comparison with other types of magnetic sensors. We provide an explanation and examples of many influences on measurement accuracy in a functional system (offset, temperature, hysteresis, amplitude, gain, etc.). Among other things, we were particularly interested in the architecture and methodology of designing interpolators to be integrated into systems-on-chip circuits that process sensor signals. Emphasis was also placed on existing designs of interpolators and their comparison. The work concludes with a case study and the design of voltage references, which represents one of the most important blocks of the interpolator. Finally, we present a voltage reference circuit with higher order compensation that will be less sensitive to process variations. The work ends with a discussion on the further development of voltage references as well as a summary of the entire work. dajalnik interpolacija integrirano vezje AMR senzor encoder interpolation integrated circuit AMR sensor true true false [K.
