System, controller, and method for determining conductance of an object
A system for determining a conductance of an object includes a sensor configured to emit an electromagnetic field when an excitation signal is received, wherein the electromagnetic field interacts with the object when the object is positioned within the electromagnetic field. A signal processing cir...

| description | A system for determining a conductance of an object includes a sensor configured to emit an electromagnetic field when an excitation signal is received, wherein the electromagnetic field interacts with the object when the object is positioned within the electromagnetic field. A signal processing circuit is coupled to the sensor and configured to provide an adjustable capacitance to the sensor to adjust a phase angle of a current flowing through the sensor, to generate a voltage measurement representative of a voltage across the sensor, and to generate a current measurement representative of the current flowing through the sensor. A controller is coupled to the signal processing circuit and configured to calculate an admittance of the sensor based on the voltage measurement and the current measurement, and to determine a conductance of the object based on the calculated admittance of the sensor. |
