N2 - This paper presents improved interfacing schemes for a recently reported variable reluctance-based thin planar angle sensor. The design and analysis of two inductance-based measurement schemes appropriate for the planar angle sensor are presented. The first one is based on differential measurement, and the second method realizes a ratiometric measurement. The suggested interfacing circuits measure the differential or ratiometric inductances of the differential sensing coils directly from the sensor rather than measuring the individual inductances of the sensing coils separately. As a result, the sensor performs better, and measurement speed is improved ten times. Studies were conducted with a variable reluctance-based angle sensor, and the designs are validated. The functionality of the proposed circuit was verified for different rotating speeds. The worst-case linearity error for the differential measurement circuit was found to be 2.3.%, for a rotating speed close to 500 rpm.
