“…A comparison of the proposed inductance simulators with other inductance simulators [31][32][33]44,[46][47][48][49][50][51][52][53][54][55][56][57][58][59][60], is shown in Table 3. It can be seen that most of the simple inductance simulators using one active building block only perform grounded-type simulations [31,48,[57][58][59][60]. The grounded inductance simulators in [33,52,53,56] use more than one active building block.…”

“…With two active and passive elements, the proposed floating inductance simulators can perform three functions, as a lossless inductor, series inductor-resistor, and parallel inductor-resistor. However, the inductance simulators realized in [31][32][33][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] cannot perform three functions with the same number of active and passive elements. The inductance simulators in [50,55] were realized from the active building block with a multiple output terminal.…”

“…The inductance simulators in [50,55] were realized from the active building block with a multiple output terminal. The inductance simulators in [46,53,57,59] require a strict matching condition of the passive element.

This paper presents inductance simulators using the voltage differencing differential input buffered amplifier (VD-DIBA) as an active building block. Three types of inductance simulators, including floating lossless inductance, series inductance-resistance, and parallel inductance-resistance simulators, are proposed, in addition to their application to the 4th order elliptic lowpass ladder filter. The simple design procedures of these inductance simulators using a circuit block diagram are also given. The proposed inductance simulators employ two VD-DIBAs and two passive elements. The complementary metal oxide semiconductor (CMOS) VD-DIBA used in this design utilizes the multiple-input metal oxide semiconductor (MOS) transistor technique in order to achieve a compact and simple structure with a minimum count of transistors. Thanks to this technique, the VD-DIBA offers high performances compared to the other CMOS structures presented in the literature. The CMOS VD-DIBAs and their applications are designed and simulated in the Cadence environment using a 0.18 µm CMOS process from Taiwan semiconductor manufacturing company (TSMC). Using a supply voltage of ±0.9 V, the linear operation of VD-DIBA is obtained over a differential input range of −0.5 V to 0.5 V. The lowpass (LP) ladder filter realized with the proposed inductance simulators shows a dynamic range (DR) of 80 dB for a total harmonic distortion (THD) of 2% at 1 kHz and a 1.8 V peak-to-peak output. In addition, the experimental results of the floating inductance simulators and their applications are obtained by using VD-DIBA constructed from the available commercial components LM13700 and AD830. The simulation results are in agreement with the experimental ones, confirming the advantages of the inductance simulators and their application.

“…To obtain FOEs featuring new values of fractional order

without re-designing the “tuned” FOE, the generalized immittance converter (GIC) may be efficiently utilized. Originally, the GIC was and still is used to emulate a classic inductor (and to obtain so called synthetic inductor) using resistors, capacitors, and selected types of active elements, e.g., operational amplifiers [ 36 ], current conveyors [ 37 ], current feedback operational amplifiers [ 38 ], etc. The utilization of GIC in designing factional-order elements was also discussed e.g., in [ 39 , 40 , 41 , 42 , 43 ], where Antoniou’s GIC employing operational amplifiers is used.…”

In this paper a concept for the efficient design of a series of floating fractional-order elements (FOEs) is proposed. Using even single or a very limited number of so-called “seed” FOEs it is possible to obtain a wide set of new FOEs featuring fractional order α being in the range [−n,n], where n is an arbitrary integer number, and hence enables to overcome the lack of commercial unavailability of FOEs. The systematic design stems from the utilization of a general immittance converter (GIC), whereas the concept is further developed by proposing a general circuit structure of the GIC that employs operational transconductance amplifiers (OTAs) as active elements. To show the efficiency of the presented approach, the use of only up to two “seed” FOEs with a properly selected fractional order αseed as passive elements results in the design of a series of 51 FOEs with different α being in the range [−2,2] that may find their utilization in sensor applications and the design of analog signal processing blocks. Comprehensive analysis of the proposed GIC is given, whereas the effect of parasitic properties of the assumed active elements is determined and the optimization process described to improve the overall performance of the GIC. Using OTAs designed in 0.18 μμm TSMC CMOS technology, Cadence Virtuoso post-layout simulation results of the GIC are presented that prove its operability, performance optimization, and robustness of the proposed design concept.

“…Recently, a considerable literature has grown up the theme of active inductance realization. Several active inductance simulators have been proposed such as operational transconductance amplifier (OTA) [1][2][3], operational transresistance amplifier (OTRA) [4,5], current-feedback operational amplifier (CFOA) [6][7][8][9][10][11][12] current differencing buffer amplifer (CDBA) [13,14], four terminal floating nullor (FTFN) [15], voltage differencing buffer amplifer (VDBA) [16][17][18], differential voltage current conveyor (DVCC) [19], second generation current conveyor (CCII) [20,21], dual-X current conveyor (DXCCII) [22][23][24]. Most of the reported circuits are commercially unavailable such as OTRA, CDBA, DVCC, DXCCII.…”

Active elements are critical in implementing active filters, oscillators, rectifiers, and signal processing circuits. We observe that several active circuits have been proposed in the literature. In this study, we have proposed four inductance simulators that employ only one active circuit current feedback operational amplifier and three or four passive components. The first and fourth topologies are designed for series lossy inductance, whereas the second and third topologies are designed for lossless negative inductance simulators. A passive RLC filter is used to demonstrate the effectiveness of the proposed inductance simulators. The simulations performed with the LTSpice program and the results agree with the theoretical analysis.
