Abstract

A method for measuring a capacitance of a device under test is provided that includes selectively charging and discharging a first conductor with a first set of p and n element-pairs in response to a voltage potential applied to the first set of p and n element-pairs. The method further includes selectively charging and discharging a second conductor with a second set of p and n element-pairs in response to a voltage potential applied to the second set of p and n element-pairs. Currents are measured at drains associated with the first set of p element-pairs as the first and second conductors charge and discharge such that a capacitance associated with the first conductor may be determined that is based on the drain currents.
