Current Mode Fractional Order Filters Using VDTAs with Grounded Capacitors

International Journal of Electronics and Telecommunications, 2019
In this work, the design of current mode Fractional order filter using VDTAs (Voltage differencing trans-conductance amplifier) as an active element with grounded capacitors has been proposed. The approximate transfer functions of low and high pass filters of fractional order on the basis of the integer order transfer has been shown and the form of ...

Arterial Viscoelastic Model using Lumped Parameter Circuit With Fractional-Order Capacitor [PDF]

2018 IEEE 61st International Midwest Symposium on Circuits and Systems (MWSCAS), 2018
Cardiovascular diseases are deemed to be the underlying source of mortality globally. Modeling the systemic arterial system is of a vital importance in the diagnosis and assessment of cardiac pathophysiology. In this work, we explore the fractional viscoelastic properties of the arterial blood vessel, and present a fractional-order lumped parameter ...

Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

Advanced Functional Materials, EarlyView.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

Linear and nonlinear capacitive coupling of electro-opto-mechanical photonic crystal cavities [PDF]

, 2014
We fabricate and characterize a microscale silicon electro-opto-mechanical system whose mechanical motion is coupled capacitively to an electrical circuit and optically via radiation pressure to a photonic crystal cavity.

Non-existence of periodic solutions in fractional-order dynamical systems and a remarkable difference between integer and fractional-order derivatives of periodic functions

, 2011
Using the Mellin transform approach, it is shown that, in contrast with integer-order derivatives, the fractional-order derivative of a periodic function cannot be a function with the same period.

Observability of counterpropagating modes at fractional-quantum-Hall edges [PDF]

, 1998
When the bulk filling factor is equal to 1 - 1/m with m odd, at least one counterpropagating chiral collective mode occurs simultaneously with magnetoplasmons at the edge of fractional-quantum-Hall samples. Initial experimental searches for an additional

Wideband Substrate Integrated Waveguide Chip Filter Using Spoof Surface Plasmon Polariton

Micromachines, 2022
This article presents a novel wideband bandpass filter based on the integration of a substrate integrated waveguide (SIW) and a spoof surface plasmon polariton (SSPP). An SIW cavity with periodic arrays of meander-slot units is etched on the top metallic

Optimized Quality Factor of Fractional Order Analog Filters with Band-Pass and Band-Stop Characteristics

, 2012
Fractional order (FO) filters have been investigated in this paper, with band-pass (BP) and band-stop (BS) characteristics, which can not be achieved with conventional integer order filters with orders lesser then two.
