In the paper, an analysis of the state-of-the-art of active elements for analog signal
processing is presented which support–in contrast to the conventional operational amplifiers …

This paper traces the history of the evolution of inverse analog filters (IAF) and presents a
review of the progress made in this area to date. The paper, thus, presents the current state …

Abstract− A new active element with two current inputs and two kinds of current output,
namely the Current-Differencing Transconductance Amplifier (CDTA) is proposed. This …

The voltage differencing transconductance amplifier (VDTA) is a recently introduced active
element for analog signal processing. However, the realization of VDTA is not given by any …

A new configuration realizing first-order canonical current processing all-pass filters based
on current differencing buffered amplifier, a recently introduced active element, is proposed …

This study proposes a current mode (CM) Kerwin–Huelsman–Newcomb (KHN) filter
employing only two current differencing transconductance amplifiers (CDTA) and two …

In spite of all electronic systems prominently being dominated by digital circuits and systems,
the analog circuits have neither become obsolete nor avoidable. In fact, despite the …

This article presents a basic current-mode building block for analog signal processing,
namely current controlled current conveyor transconductance amplifier (CCCCTA). Its …

In this paper, new biquad filter configuration using a recently introduced active element,
namely Voltage Differencing Buffered Amplifier (VDBA), is proposed. This block has high …

A review of the two integrator loop oscillator circuits providing two quadrature sinusoidal
output voltages is given. All the circuits considered employ the minimum number of …
