Abstract
An example apparatus includes: calibration circuitry configured to determine a second current at a second terminal of a second impedance circuit based on a first parasitic capacitance, a first impedance value, a third impedance value, a first voltage, and a second voltage; determine a third voltage at a second terminal of a second impedance circuit based on the first parasitic capacitance, a second impedance value, the third impedance value, the second voltage, and the second current; and determine a second parasitic capacitance between the second terminal of the second impedance circuit and the second terminal of a fifth impedance circuit based on the second current, the third voltage, a third current at the second terminal of the fifth impedance circuit, and a fourth voltage at the second terminal of the fifth impedance circuit.
