Quality Factor of Capacitor: The quality factor of a capacitor is the ratio of its reactance to its series resistance, given by Q = 1 / (ωRC). Lossy Capacitor: A lossy capacitor can be modeled with a capacitance and high parallel resistance, influencing its efficiency. Every inductor has a small resistance along with its inductance.
The Q-factor or the quality factor of a capacitor at the operating frequency ω is defined as the ratio of the reactance of the capacitor to its series resistance. Q = (X C / R). It is a dimensionless quantity. D-Factor – The dissipation factor of a capacitor is the power loss when AC is applied through the capacitor.
Meters that use an AC source, such as LCR meters, generally provide a DC bias option to measure the value under this condition. This analysis has shown there are a lot of properties to consider when measuring the value of a capacitor.
Note that (C1 – C2) is the capacitance of interest. It may be measured separately using a C meter. If Q2 = Q1 the Q of the capacitor becomes infinite. toward zero and the detector impedance is infinite. With method 2, the measured Q is the loaded Q and a correction is required based on insertion loss to obtain the unloaded Q.
In and by only using the Quadrature-phase information, the capacitance has been measured and good measurement accuracy of 1 fF could be reached over a measurement range up to 50 fF and a dynamic range of 33.97 dB. This method should be principally immune against stray capacitances, but conductance losses could affect the measurement accuracy.
The power consumption is around 68mW. The dynamic range is 40 dB. Overall, the dual/multi-slope capacitance measurement circuits provide very high immunity to stray capacitances thanks to the virtual ground in the integrator and low impedance of the excitation signal interface.
