    Current Differencing Buffered Amplifier-Based PID Controller Design
    (World Scientific Publ Co Pte Ltd, 2021) Gür, Fethi; Anday, Fuat
    A new voltage mode Proportional-Integral-Derivative (PID) controller employing Current Differencing Buffered Amplifier (CDBA) is presented. The proposed PID controller employs a canonical number of capacitors without requiring any passive components matching conditions. The element values are expressed in terms of PID parameters. Workability of the proposed controller is demonstrated through SPICE simulations for which CDBA is realized using Current Feedback Amplifier (CFA). The simulation results are found in close agreement with the theoretical results.

    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.
