Abstract
A system may include a resistive-inductive-capacitive sensor, a driver configured to drive the resistive-inductive-capacitive sensor with a driving signal at a driving frequency, and a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor and configured to, during a calibration phase of the measurement circuit, measure phase and amplitude information associated with the resistive-inductive-capacitive sensor and based on the phase and amplitude information, determine at least one of a resonant frequency of the resistive-inductive-capacitive sensor and a transfer function of the resistive-inductive-capacitive sensor.
