Abstract
Inductance values are measured though the use of a charge transfer based measurement system. During a first phase, a target inductor is connected to an energy source to allow current through an inductor to increase. In a second phase, the inductor is disconnected from the energy source, to allow the current to decrease, and to facilitate transfer of charge to a capacitor. The phases may be repeated, and a count is kept of the number of repetitions.
