Abstract
The impedance characteristics of three different type of fractional-order capacitors (FOCs) with an order of -0.74, -0.79, and -0.91 are analyzed. The used devices have excellent feature such as constant phase angle in the frequency range 10 MHz-100 MHz. Their impedance data is fitted with second-order passive electrical model structures of Foster-I and Foster-H using standard ER-48 compliant component values and obtained results are evaluated i.e. relative magnitude and phase error. The effect on phase and pseudo-capacitance using a detailed experimental study of series-, parallel-, and interconnected FOCs is also shown.
