| Abstract(in English) | A new type of small magnetic rotary encoder is presented. The encoder using CMOS magnetic sensors (MAGFET) arrays in a square arrangement detects the magnetic field of a permanent magnet attached to the end of the rotating shaft. The sensor array is integrated onto a CMOS chip together with angle-detection circuits, leading to the realization of a compact, cost-effective rotary encoder. A prototype sensor chip in 0.8μm thechnology with dimensions of 4.3 × 4.3 mm^2 has the error of ± 3.5° without offset calibration and ± 0.36° with offset calibration, based on an angle calculation method with mean square estimation. This means that the CMOS rotary encoder can achieve resolution of 10 bits per rotation at the cost of calibration. |
