The sensitivity of a method to predict a capacitor's frequency characteristic

A joint effort between the U.S. Naval Academy and the National Institute of Standard and Technology (NIST) resulted in the development of a method to characterize the capacitance and dissipation factor of a set of commercial standard four terminal-pair (4TP) capacitors. The method depends on network analyzer impedance measurements at high frequencies (40 MH–200 MHz) and a regression of these measurements down to the frequency range of 10 MHz–1 kHz. This paper provides an analysis of the sensitivity of the regression parameters and the high-frequency impedance measurements.
