Abstract:
A system may include a resistive-inductive-capacitive sensor, a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor and configured to measure phase information associated with the resistive-inductive-capacitive sensor and based on the phase information, determine a displacement of a mechanical member relative to the resistive-inductive-capacitive sensor. The system may also include a Q factor enhancer communicatively coupled to the resistive-inductive-capacitive sensor and configured to control a Q factor of the resistive-inductive-capacitive sensor.
