FVF based CDTA and Its application

2012 International Conference on Communication, Information & Computing Technology (ICCICT), 2012
This paper presents a modified CMOS implementation of the current differencing trans-conductance amplifier (CDTA). It uses one current source and one current sink to get the current differencing action. The proposed circuit uses lesser number of transistors, offers higher bandwidth, apart from other qualities associated with them.

CDTA Based Multimode SIMO Biquad Filter

2020 International Conference on Communication and Signal Processing (ICCSP), 2020
In this paper, Current Differencing Transconductance Amplifier (CDTA) based multimode single input multiple output (SIMO) biquadratic filter is presented. The developed circuit uses three CDTAs, two grounded capacitors, one grounded resistor, and one virtually grounded resistor. The realized filter has one input and three outputs, which are lowpass (LP)

CDTA: A Cross-Domain Transfer-Based Attack with Contrastive Learning

Proceedings of the AAAI Conference on Artificial Intelligence, 2023
Despite the excellent performance, deep neural networks (DNNs) have been shown to be vulnerable to adversarial examples. Besides, these examples are often transferable among different models. In other words, the same adversarial example can fool multiple models with different architectures at the same time.

Multistep Oxidation Kinetics of [FeII(cdta)] [cdta = N,N,N,N-(1,2-Cyclohexanediamine)tetraacetate] with Molecular Oxygen

European Journal of Inorganic Chemistry, 1999
The complicated oxidation kinetics of the reaction of [FeII(cdta)] [cdta = 1,2-(N,N′- cyclohexanediamine)tetraacetate] with molecular oxygen was investigated as a function of [FeII], [O2], pH, temperature and pressure. In the presence of an excess of [FeII(cdta)] three steps could be observed, for which the following rate constants were found at 25°C ...

Realization of CDTA based frequency agile filter

2013 IEEE International Conference on Signal Processing, Computing and Control (ISPCC), 2013
This paper presents frequency agile filter based on current difference transconductance amplifier (CDTA). The agile filters used in this work provide high agilty, tunability and quality factor while they are fully integrated configurations and not discrete systems.

Evaluation of the Effect of EDTAC, CDTA, and EGTA on Radicular Dentin Microhardness

Journal of Endodontics, 2001
The effect of EDTAC (ethylenediamine tetra-acetic acid plus Cetavion, an ammonium surfactant), CDTA (cyclohexane-1,2-diaminetetra-acetic acid), and EGTA (ethylene glycol-bis-(beta-amino-ethyl ether) N,N,N',N'-tetra-acetic acid) on the microhardness of radicular dentin of the cervical third of human teeth was studied.

A Current-Mode Wheatstone Bridge Employing Only Single DO-CDTA

APCCAS 2008 - 2008 IEEE Asia Pacific Conference on Circuits and Systems, 2008
This article proposes a topology of current-mode improved Wheatstone bridge based on dual-output current differencing transconductance amplifier (DO-CDTA). The features of the proposed configuration are that: magnitude of output signal can be controlled via the input bias currents; the proposed circuit is low temperature sensitive, the circuit ...
