초록

본 논문에서는 IoT 응용에서 사용되는 인덕티브한 센서의 인덕턴스를 측정할 수 있는 회로를 제안하였다. RL 저역 통과 필터 회로, 비교기, 전류 제어 스위치, 커패시터의 특성을 이용하여 회로를 구성하였으며, RL 저역 통과 필터 회로의 출력 전압이 기준 전압보다 큰 duration time을 통해 1nH-1H 범위 내의 인덕턴스 값을 도출 할 수 있다.

This paper propose a circuit that can measure the inductance of an inductive sensor used in IOT applications. The circuit was constructed using the characteristics of an RL low-pass filter circuit, comparator, current control switch, and capacitor, and the inductance value within the range 1[nH] < L ≤ 1[H] can be derived through the duration time during the output voltage of the RL low-pass filter circuit is greater than the reference voltage.
