History, Progress and New Results in Synthetic Passive Element Design Employing CFTAs
(International Society for Science and Engineering, 2015-03-31)
After the presentation of the Current Follower Transconductance Amplifier (CFTA) active element, it has found a numerous application possibilities while designing linear and non-linear analog function blocks. This paper ...
New Resistorless and Electronically Tunable Realization of Dual-Output VM All-Pass Filter Using VDIBA
(Springer, 2013-01-07)
In this paper, a new active element called voltage differencing inverting buffered amplifier (VDIBA) is presented. Using single VDIBA and a capacitor, a new resistorless voltage-mode (VM) first-order all-pass filter (APF) ...
New voltage-mode universal filter and sinusoidal oscillator using only single DBTA
(Taylor & Francis, 2010-04-01)
In this article, a new voltage-mode second-order universal frequency filter and sinusoidal oscillator using only single differential-input buffered and transconductance amplifier (DBTA) is presented. The proposed voltage-mode ...
Realisations of single-resistance-controlled quadrature oscillators using a generalised current follower transconductance amplifier and a unity-gain voltage-follower
(Taylor & Francis, 2010-08-01)
This article presents realisations of single-resistance-controlled-oscillators (SRCOs) using the recently proposed modern active building block (ABB), namely the generalised current follower transconductance amplifier ...
An Additional Approach to Model Current Followers and Amplifiers with Electronically Controllable Parameters from Commercially Available ICs
(Versita, 2012-11-22)
Several behavioral models of current active elements for experimental purposes are introduced in this paper. These models are based on commercially available devices. They are suitable for experimental tests of current- ...
CMOS-based active RC sinusoidal oscillator with four-phase quadrature outputs and single-resistance-controlled (SRC) tuning laws
(Elsevier, 2012-09-07)
This paper proposes a very compact CMOS realization of active RC sinusoidal oscillator capable of generating four quadrature voltage outputs. The oscillator is based on the cascade of lossless and lossy integrators in loop. ...
New resistorless tunable voltage-mode universal filter using single VDIBA
(Springer, 2013-08-01)
To increase the universality of the recently introduced voltage differencing inverting buffered amplifier (VDIBA), this letter presents a new voltage-mode (VM) multi-input–single-output (MISO) universal filter. The proposed ...
Realization of first-order current-mode filters with low number of MOS transistors
(World Scientific Publishing Company, 2013-01-14)
In this paper, a new current-mode (CM) circuit for realizing all of the first-order filter responses is suggested. The proposed configuration contains low number of components, only two NMOS transistors both operating in ...
Three-input-one-output current-mode universal biquadratic filter using one differential difference current conveyor
(NISCAIR ONLINE PERIODICALS REPOSITORY (NOPR), 2014-08-01)
A current-mode universal biquadratic filter is presented. The architecture has three input terminals, one output terminal using one differential difference current conveyor (DDCC), two grounded capacitors and two resistors. ...
Reconfigurable Fractional-Order Filter with Electronically Controllable Slope of Attenuation, Pole Frequency and Type of Approximation
(World Scientific Publishing, 2017-03-09)
This paper presents design of electronically reconfigurable fractional-order filter that is able to be configured to operate as fractional-order low-pass filter (FLPF) or fractional-order high-pass filter (FHPF). Its slope ...
