This disclosure describes circuits and techniques for determining inductance on an electrical line. In some examples, a method comprises charging a capacitor in time steps to a voltage level; counting a number of the time steps to the voltage level, wherein the number of the time steps defines a coarse measurement inductance of the electrical line; measuring a charging rate associated with charging the capacitor within a measurement window that is defined at the voltage level, wherein the charging rate associated with charging the capacitor within the measurement window defines a fine measurement of the inductance of the electrical line; and outputting an indication of the number of time steps and an indication of the charging rate associated with charging the capacitor within the measurement window.
