The present invention relates to an inductive sensor circuit. The inductive sensor circuit according to one embodiment of the present invention for improving the response speed of a sensor comprises: a detection circuit unit comprising a condenser, which is connected in parallel to the inductor of the sensor and forms an oscillation circuit, a first operational amplifier for receiving as an input and amplifying the electrical signal of an oscillation waveform generated by the oscillation circuit, a filter unit for receiving as an input, rectifying, and smoothing the electrical signal amplified by the first operational amplifier, and a first control unit for converting into a first digital signal and outputting the electrical signal rectified and smoothed by the filter unit; a linearization circuit unit comprising a second control unit for receiving as an input an analogue signal measured by the micrometer of the sensor, converting same into a second digital signal, comparing the second digital signal with the
