Abstract
A circuit for determination of a resistance of an array of capacitive elements includes a reference ring oscillator circuit, the reference ring oscillator circuit being loaded with low-loss capacitive elements; an array test ring oscillator circuit, the array test ring oscillator circuit being loaded with the array of capacitive elements; and a resistance determination module, the resistance determination module configured to determine the resistance of the array of capacitive elements based on data from the reference ring oscillator circuit and the array test ring oscillator circuit.
