Implementation of a Shadow Filter using CFCC

2021 2nd International Conference for Emerging Technology (INCET), 2021
In this paper a new shadow filter implementation has been designed using Current Follower Current Conveyor (CFCC) block and grounded elements. Shadow filter allows for electronically tunable filter parameters by simply varying the gain of an external amplifier in the feedback path and without disturbing the core filter circuit.

Realization of current mode universal shadow filter

AEU - International Journal of Electronics and Communications, 2020
Abstract In this paper, a current-mode universal shadow filter is proposed using a new variant of current differencing transconductance amplifier (CDTA), namely current controlled current differencing cascaded transconductance amplifier (CC-CDCTA) and two capacitors.

New voltage-mode bandpass shadow filter

2016 13th International Multi-Conference on Systems, Signals & Devices (SSD), 2016
A new voltage-mode bandpass shadow filter is presented. The filter is built around the current-feedback operational-amplifier. The parameters of the filter can be controlled by adjusting the gains of external amplifiers built around the current-feedback operational-amplifier.

New CFOA-based shadow banpass filter

2016 International Conference on Electronics, Information, and Communications (ICEIC), 2016
This paper presents a new topology for implementing a bandpass shadow filter using the current-feedback operational amplifier (CFOA). The proposed circuit uses CFOAs, and avoids the use of external summing circuit to implement a shadow bandpass filter with controlled center frequency. Experimental results obtained using the AD844 CFOA are included.

Generalization of shadow filters in fractional domain

International Journal of Circuit Theory and Applications, 2021
AbstractThis work is intended to generalize the design of shadow filters to the fractional‐order domain. Shadow filters, in integer‐order domain, introduced by Lakys and Fabre, consist of an external amplifier in the feedback loop of the basic filter cell and by varying the gain of this amplifier the parameters of the resulting filter are modified ...

Boosting the Quality Factor of the Shadow Bandpass Filter

Journal of Circuits, Systems and Computers, 2022
This paper proposes a new method to increase the quality factor of the shadow bandpass filter. The proposed circuit topology is simple, with the use of conventional biquad cell along with external amplifiers. The major advantageous feature is that the quality factor of the filter is boosted up whereas the gain of the external amplifier is ...
