Grounded Fractional Order Notch Filter using CPZ Adjustable Obtuse Angle Capacitive Fractor

Year: 2026

Type: conference-paper

Abstract: This paper presents the design of a grounded fractional order notch filter (FONF). The proposed FONF is designed with a resistor, an inductor, and an obtuse angle capacitive fractor. The notch action of the proposed circuit generates from its inherent series resonating action. The resonating frequency can be tuned by adjusting the value of the fractance and the resistor together. The notch frequency of the proposed notch filter follows the resonating frequency closely. The required obtuse angle fractor is designed using the Bruton’s GIC circuit. The GIC resistor allows to adjust the fractance value as required. The paper also include the experimental results of proposed FONF with notch frequency 1.2 kHz, attenuation of 41 dB and Q factor 55.
