Öğe CIM a current inverting metamutator and its application to universal filters among others(IEEE, 2017) Minayi, Elham; Göknar, İzzet CemA new kind of metamutator namely "Current Inverting Metamutator," its realizations using different types of active blocks and some of its applications are given in this paper. As a classical application of the metamutator simulation of a memristor and, as an original application, several schemes realizing universal filters are proposed. The post-layout characteristics of both applications, using TSMC 0.13 mu m process parameters with +/- 0.75 V power supply voltage, are presented to confirm the theoretical analysis.Öğe Current inverting metamutator, its implementation with a new single active device and applications(2018-10) Minayi, Elham; Göknar, İzzet CemA new kind of metamutator, namely "Current Inverting Metamutator", its realizations using different types of active blocks and some of its applications like voltage-mode universal biquadratic filter with three input and one output terminals are presented. The proposed circuits can realize all standard filters, namely, low-pass, band-pass, high-pass, notch and all-pass without passive component matching conditions. The proposed circuit offers the features of using grounded capacitors and orthogonal controllability of angular frequency and quality factor. Then a novel realization of metamutator with one active device, additive and differential IC (AD-IC) is proposed and implemented with twelve transistors only. The metamutator with AD-IC has the advantages: (1) of creating new realizations of memristors, capacitance multipliers, inductor simulators, frequency dependent negative resistors which can be used to make IC active filters, (2) less is the number (only one) of active devices, less is the amount of disparity, (3) no need to match passive component values.Öğe Current inverting metamutator, its implementation with a new single active device and applications (vol 97, pg 15, 2019)(Springer, 2019-11) Minayi, Elham; Göknar, İzzet CemVoltage Inverting Metamutator (VIM) and Current.Öğe Metamutator based universal, single input multi output current mode filter(John Wiley and Sons Ltd, 2023-03) Göknar, İzzet Cem; Minayi, ElhamThe introduction of Add - Differentiate IC, AD-IC, a new integrated circuit, into schemes for realizing single input multiple output current mode filters is the motivation behind this paper. In the circuit structure of this filter with only one active device with a minimal number of transistors and five passive components are being used. Non ideal effects of the design are investigated and simulation results of the application, using TSMC 0.25 ?m process parameters with ±1.25 V power supply voltage and the bias (Formula presented.) as 0.8 V resulting in 0.99 mW power dissipation for the entire filter, are also presented to confirm the theoretical analysis. With this new design technique, the tunabilities of the angular frequency ((Formula presented.)) and quality factor ((Formula presented.)) can be performed independently.Öğe Metamutator: Its Realizations and Its Applications(Işık Üniversitesi, 2019-07-22) Minayi, Elham; Göknar, İzzet Cem; Işık Üniversitesi, Fen Bilimleri Enstitüsü, Elektronik Mühendisliği Doktora ProgramıMutators became very popular after 1971, when Leon Chua realized the memristor, his postulated fourth circuit element, using them. The reason for the popularity of mutators, which are easily realizable 2-port devices, lies in the fact that they render possible the simulation/emulation of, hence experimentation with, postulated non-existing (not o the shelf available) elements like memstors.1 On the other hand, in the literature when simulating/emulating elements with 2- ports, many 4-port \generalized mutator-like" realizations that nobody has been able to identify are being used. These underlying 4-ports, and their ability to act as a mutator when two of the ports are properly terminated, have been thus named metamutator. In this thesis, in addition to introducing some of metamutator realizations, newly designed metamutator circuits with one or two active devices are introduced. Also, a new active device, with only twelve transistors, named Additive and Differential IC (AD-IC), is proposed with its layout and use in metamutator circuit design. In addition, many 1-port and 2-port circuit realizations using metamutators have been introduced. 1-port applications are memstor simulation/emulation, oating and/or grounded impedance scaling which comprise inductance simulation, capacitance multiplication, oscillators and Frequency Dependent Negative Resistor (FDNR) simulation. 2- port applications cover Voltage Mode Multiple Input Single Output (VM-MISO) and Current Mode Single Input Multiple Output (CM-SIMO) universal lters and implementations of transconductance and transimpedance ampli ers. Also, two di erent applications of AD-IC: ADIC based analog multiplier and AD-IC based full-wave recti er are proposed in the thesis.Öğe A rectifier circuit using add-differentiate IC with a minimal number of CMOS transistors(IEEE, 2018) Göknar, İzzet Cem; Minayi, ElhamUsing the recently developed Add-Differentiate 5-terminal Integrated Circuit, AD-IC (which possess 12 CMOS transistors only), augmented with two diodes, a new rectifier configuration is presented. Transistor level circuit and its layout are provided and the rectifier is simulated with parameters extracted from the layout showing very good conformity with desired rectifier behavior. Finally, a table of comparison of the proposed rectifier with fourteen others, existing in the literature, is included to conclude the paper.Öğe Single active device metamutator; Its application to impedance simulation and in particular to FDNR(IEEE, 2017) Minayi, Elham; Göknar, İzzet Cemhe proposed Metamutator configuration employs only one Fully Differential Current Conveyor (FDCCII) which has 9 terminals including ground. By properly interconnecting these terminals a 4-port Metamutator is obtained without use of any other external element. It maintains the following advantages: (i) use of only one active element: less is the number of active devices less is the amount of disparity, (ii) possibility of realizing Memristors, Capacitors, Inductors, Frequency Dependent Negative Resistor (FDNR), which can be used to make integrated circuit active filters, (iii) no need to impose component choice constraints. SPICE simulations' results using TSMC 0.18 mu m CMOS process parameters and +/- 0.9V supply voltages validate the theoretical predictions.
