Series-, Parallel-, and Inter-Connection of Solid-State Arbitrary Fractional-Order Capacitors: Theoretical Study and Experimental Verification
In the paper, general analytical formulas are introduced for the determination of equivalent impedance, magnitude, and phase, i.e. order, for n arbitrary fractional-order capacitors (FoCs) connected in series, parallel, ...
Compact MOS-RC Voltage-Mode Fractional-Order Oscillator Design
A new voltage-mode fractional-order oscillator, employing in total 12 Metal-Oxide-Semiconductor (MOS) transistors, is introduced in this paper. The proposed circuit is composed of two operational transconductance amplifiers, ...
Validation of Fractional-Order Lowpass Elliptic Responses of (1 + )-Order Analog Filters
In this paper, fractional-order transfer functions to approximate the passband and stopband ripple characteristics of a second-order elliptic lowpass filter are designed and validated. The necessary coefficients for these ...
VDIBA-Based Fractional-Order Oscillator Design
This paper deals with a voltage-mode integer- and fractional-order oscillator design providing compact and simple CMOS structure. The proposed circuit consists of only one grounded/floating capacitor, one grounded/floating ...
Comparative Study of Op-Amp-based Integrators Suitable for Fractional-Order Controller Design
In this paper, a fractional-order capacitor (FOC) of an order = 0.89 (i.e. constant phase angle –80.1 degree) was emulated via Valsa RC network with five branches. The network component values were optimized using modified ...
Identification and Monitoring of Parkinson’s Disease Dysgraphia Based on Fractional-Order Derivatives of Online Handwriting
Parkinson’s disease dysgraphia affects the majority of Parkinson’s disease (PD) patients and is the result of handwriting abnormalities mainly caused by motor dysfunctions. Several effective approaches to quantitative PD ...
