Abstract: A sensor circuit has coils 3a, 3b whose inductances change in response to a change in a physical quantity. A drive circuit 4A applies an a.c. drive voltage to the coils. A voltage detector circuit 5 senses the voltage across each coil. A current integration circuit 10 integrates the current through each coil starting at the time of a polarity inversion of the drive voltage, and outputs a control signal C1, C2 until the time the integrated value of the coil current becomes zero. A phase detector circuit 6A detects the coil voltage to generate a detection voltage Vd during the time the current integration circuit outputs the control signal. A smoothing circuit 7 processes the detection voltage to output a mean voltage Vm. The sensor circuit eliminates any adverse effects of the internal resistances of the coils by inverting and offsetting the resistive component of the coil voltage during the detection period.
