Abstract
A novel smart resistive-capacitive angular position sensor is presente d. The main advantages of this low-cost system are its simplicity, hig h stability and high reliability. A very linear oscillator is used in the processing circuit to convert the position quantity to a period-mo dulated signal which can directly be read out by a microcontroller. Th e system does not need an A/D converter. The nonlinearity of the smart angular position sensor system is less than +/-0.3% (+/-0.9 degrees) over the range of 270 degrees.
