Abstract: In some examples, a method includes controlling a first set of switches to deliver a first voltage signal through a first set of capacitors to a common node. The method also includes controlling a second set of switches to deliver a second voltage signal through a second set of capacitors to the common node, wherein the first set of capacitors is electrically connected to the second set of capacitors by the common node. The method further includes measuring a time duration to discharge the common node. The second voltage signal includes an opposing polarity to the first voltage signal.
