1. A resistance-to-digital converter comprising:

  • an oscillator that is connected to a target resistor whose resistance is to be subjected to digital conversion, and that oscillates at an oscillation frequency corresponding to the resistance of the target resistor;

    time period counting means for counting a clock signal to determine a predetermined time period; and

    oscillation output counting means for counting an oscillation output of said oscillator during the predetermined time period, and for outputting its count value as a digital value corresponding to the resistance of the target resistor.
