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- ...

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 ...

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 ...

Presented work deals with applications of the single Z-Copy Controlled-Gain Voltage Differencing Current Conveyor (ZC-CG-VDCC) in single purpose and multifunctional biquadratic voltage- and current-mode active resistor-less ...

The paper presents a proposal of modified 2ndorder fully-differential universal frequency filter. Both the pole frequency and quality factor (controlled without disturbing each other) of the filter can be controlled by two ...

This work presents an example of implementation of electronically controllable features to an originally unsuitable circuit structure of oscillator. Basic structure does not allow any electronic control and has mutually ...

The main aim of this paper is to present solution of triple-input single-output (TISO) filter with independently adjustable pole frequency, quality factor, bandwidth and also gain. Filter is universal, operates in current ...

The second order universal voltage-mode filter using voltage differencing differential difference amplifiers (VDDDAs) has been proposed. It has high input impedance voltage-mode biquad filter with orthogonal tune of natural ...

This paper presents the simulations results in comparison with the measured results of the practical realization of the multifunctional second order frequency filter with a Digitally Controlled Current Amplifier (DACA) and ...

This paper presents an universal filter with control of the pole frequency by two mutually independent parameters - current gain (B) and intrinsic resistance (R x) in frame of two modified current differencing unit (MCDU) ...
