Abstract
A method of interfacing an LC sensor with a control unit is described. The control unit may include first and second contacts, and the LC sensor may be connected between the first and second contacts. The method may include starting the oscillation of the LC sensor, and monitoring the voltage at the second contact, in which the voltage at the second contact corresponds to the sum of the voltage at the first contact and the voltage at the LC sensor. The voltage at the first contact may be varied such that the voltage at the second contact does not exceed an upper voltage threshold and does not fall below a lower voltage threshold.
