Claim Text:
1. A method for characterizing or measuring a first capacitance, comprising: electrically coupling a first terminal of the first capacitance to a first mid-point of a first capacitive voltage divider bridge that is in parallel with a second capacitive voltage divider bridge, the second capacitive voltage divider bridge comprising a second mid-point, the first and second capacitive voltage divider bridges being electrically coupled at first and second shared nodes, said first and second mid-points being positioned between said first and second shared nodes; applying a first voltage to a second terminal of the first capacitance; applying a bias voltage to the capacitive voltage divider bridges; maintaining a voltage of the first mid-point near a reference voltage; discharging the second mid-point with a constant current; and in response to a voltage of the second mid-point reaching a first voltage threshold:
