用于对接LC传感器的方法和相关系统
摘要：
本申请涉及用于对接LC传感器的方法和相关系统。提供一种将LC传感器和控制单元进行对接的方法。控制单元可以包括第一接触和第二接触，其中LC传感器连接在第一接触和第二接触之间。电容器连接在第一接触和接地之间。为了开始LC传感器的振荡，所述方法可以包括：在第一阶段期间，将第一接触连接到电源电压并且将第二接触置于高阻抗状态，从而使得电容器通过电源电压而被充电。在第二阶段期间，将第一接触置于高阻抗状态，并且将第二接触连接到接地，从而使得电容器将电荷朝向LC传感器转移。在第三阶段期间，第一接触和第二接触可以置于高阻抗状态，因此LC传感器能够进行振荡。
摘要（英）：

A method of interfacing a LC sensor (10) with a control unit (20) is described. Specifically, the control unit comprises a first (202) and a second (204) contact, wherein the LC sensor (10) is connected between the first (202) and the second (204) contact, and wherein a capacitor (C1) is connected between the first contact (202) and a ground (GND). In particular, in order to start the oscillation of the LC sensor, the method comprising the steps of: - during a first phase, connecting the first contact (202) to a supply voltage (VDD) and placing the second contact (204) in a high impedance state, such that the capacitor (C1) is charged through the supply voltage (VDD); - during a second phase (2004), placing the first contact (202) in a high impedance state and connecting the second contact (204) to the ground (GND), such that the capacitor (C1) transfers charge towards the LC sensor (10); and - during a third phase (2006), placing the first contact (202) and the second contact (204) in a high impedance state, such that the LC sensor (10) is able to oscillate.
