Electronically Adjustable Emulator of the Fractional-Order Capacitor
(Kaunas University of Technology, 2019-12-12)
This paper presents a design of the controllable emulator of the FOC (Fractional-Order Capacitor) and its application. The circuit is based on 5th-order RC topology (type Foster I) where the passive elements in the topology ...
Practical Design of Fractional-Order Oscillator Employing Simple Resonator and Negative Resistor
This contribution presents straightforward design of a fractional-order oscillator employing novel simple impedance inverter (implementing differential voltage current conveyor transconductance amplifier as active element) ...
Reconfigurable Fractional-Order Filter with Electronically Controllable Slope of Attenuation, Pole Frequency and Type of Approximation
(World Scientific Publishing, 2017-03-09)
This paper presents design of electronically reconfigurable fractional-order filter that is able to be configured to operate as fractional-order low-pass filter (FLPF) or fractional-order high-pass filter (FHPF). Its slope ...
Dual-parameter control of the pole frequency in case of universal filter with MCDU elements
This paper presents an universal filter with control of the pole frequency by two mutually independent parameters - current gain (B) and intrinsic resistance (R x) in frame of two modified current differencing unit (MCDU) ...
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 ...
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 ...
