A universal active biquad based on the dual-output second-generation current-conveyor (CCII±) is presented. The circuit uses only six CCII± and can, simultaneously, support three mixed-mode transfer functions and five current-mode transfer functions. The circuit uses grounded resistors and capacitors and enjoys independent grounded-element control of the filter parameters.

This paper presents a versatile universal current-mode and transresistance-mode biquadratic filter using only two multiple outputs second-generation current conveyors (MOCCIIs), two grounded capacitors, and three grounded resistors. The proposed configuration can realize all five standard filtering functions from one current-output terminal and one voltage-output terminal, and also provide all these filtering functions from different current-output and voltage-output terminals without changing the filter topology. Moreover, the proposed biquad filter still achieves many advantages like the employment of all grounded passive components, and the minimum number of active component counts, in addition to having no need of inverting-type input signals or double-type input signals for the use of special input signals, high output impedance and low sensitivity performance. H-Spice simulation results confirm the theory.

This article given a second generation current controlled current conveyor positive (CCCII+), second generation current controlled current conveyor negative (CCCII-), Quadrature oscillator with high-Q frequency choosing network and implementing completely different phase oscillators by employing (CCCII+) positive and (CCCII-) negative, and high band pass filter network, the approach is predicted on the CMOS technology . The root of this concept is, considering a customary voltage mode oscillator which consists of band pass filter with prime quality issue (high-Q) and voltage mode amplifier is transfigure into current mode oscillator by replacing tans-conductance amplifier. Because the loop of the oscillator is has lavish selectivity, the oscillator process less distortion. In addition 3dB bandwidth, oscillating condition, oscillation frequency of the oscillator could linearly, independently and electronically be tuned by adjusting the bias current of the (CCCII±)[1], lastly different simulations have been carried out to verify the linearity between output and input ports, range of frequency operations. These results can justify that the designed circuits are workable.

Abstract 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 Adjustable Current Amplifier (DACA) and two Dual-Output Controllable Current Conveyors (CCCII +/−). This filter is designed for use in current mode. The filter was designed of the single input multiple outputs (SIMO) type, therefore it has only one input and three outputs with individual filtering functions. DACA element used in a newly proposed circuit is present in form of an integrated chip and the current conveyors are implemented using the Universal Current Conveyor (UCC) chip with designation UCC-N1B. Proposed frequency filter enables independent control of the pole frequency using parameters of two current conveyors and also independent control of the quality factor by change of a current gain of DACA.
