    Current mode leapfrog ladder filters using a new active block
    (ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2010) Ayten, Umut E.; Sagbas, Mehmet; Sedef, Herman
    In this paper, a new multi-terminal active component, namely current backward transconductance amplifier (CBTA) is proposed. The design procedure for the systematic realization of current-mode ladder filters using proposed active component is also presented. In order to demonstrate that the CBTA considerably simplifies the leapfrog structure of the current-mode ladder filters, a fifth-order Butterworth low-pass filter that requires a minimum of active components is presented. The theoretical results are demonstrated by using PSPICE simulation. (C) 2009 Elsevier GmbH. All rights reserved.

    Current-Mode SITO Filter Using a Single Active Component
    (IEEE, 2009) Ayten, Umut Engin; Sagbas, Mehmet; Sedef, Herman
    In this paper, current-mode filter using new active component, namely; current backward transconductance amplifier (CBTA) is presented. The proposed filter uses two resistors, two capacitors and only one CBTA. It has low active and passive sensitivities. The validity of the proposed circuit is demonstrated by PSPICE simulations and experimental results.

    Electronically tunable floating inductance simulator
    (ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2009) Sagbas, Mehmet; Ayten, Umut E.; Sedef, Herman; Koksal, Muhammed
    In this letter, a new floating inductance simulator circuit is presented. The proposed structure consists of only one grounded capacitor without any external resistors and two different active elements. The active elements are dual-output current-controlled current conveyor (DO-CCCII) and operational transconductance amplifier (OTA). The proposed inductance simulator can be tuned electronically by changing the biasing current of the DO-CCCIIs or by changing the current of the OTA. Moreover, the circuit does not require any conditions of component matching. It has a good sensitivity performance with respect to tracking errors. As an application, the proposed inductance simulator is used to construct a fourth-order resistively terminated LC band-pass filter. The theoretical analysis is verified by the SPICE simulation results. (C) 2008 Elsevier GmbH. All rights reserved.

    A new Pid controller circuit design using Cfoas
    (Springer, 2020) Cam Taskiran, Zehra Gulru; Sedef, Herman; Anday, Fuat
    In this study, a new CFOA-based PID controller circuit is designed and implemented by a systematic approach employing signal-flow graph theory which is a powerful tool for active circuit design. The proposed circuit has independently adjustable PID parameters (KP, KI, KD) which are independently controlled by only one passive element. Having high input and low output impedances, it has the ability to cascade with other circuits. The proposed PID circuit is examined in a closed-loop control system with an example plant circuit. Mathematical analyses are performed and discussed. The PID controller is realized by using commercially available integrated circuit elements, and results are given to demonstrate the performance of the proposed PID controller.

    Voltage Differencing Gain Amplifier-Based nth-Order Low-Pass Voltage-Mode Filter
    (WORLD SCIENTIFIC PUBL CO PTE LTD, 2018) Taskiran, Zehra Gulru Cam; Sedef, Herman; Anday, Fuat
    In this paper, a new active-C filter realizing the general nth-order low-pass voltage transfer functions using n voltage differencing gain amplifiers (VDGAs) is presented. In this realization minimum number of equal-valued grounded capacitors and n active elements are used. Due to the adjustability of the transconductance of the VDGA with current, different gains can be realized using the same building block and a simple filter structure can be created. The filter which is composed of VDGA building blocks is suitable for integration and advantageous in terms of eliminating parasitic effects because all capacitors are grounded and the filter structure has no resistors. All simulations are performed on SPICE and the accuracy of this method is validated experimentally with commercially available products upon on-board circuit.
