Resonant phase sensing of resistive-inductive-capacitive sensors

A system comprising:

• a resistive-inductive-capacitive sensor;
• a driver configured to drive the resistive-inductive-capacitive sensor with a driving signal at a driving frequency;
• a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor and configured to:
• measure phase information associated with the resistive-inductive-capacitive sensor, wherein the phase information is relative to a phase of the driving signal;
• and
• based on the phase information, determine a displacement of a mechanical member relative to the resistive-inductive-capacitive sensor, wherein the displacement of the mechanical member causes a change in an impedance of the resistive-inductive-capacitive sensor.
