CCCDTAs-based Versatile Quadrature Oscillator and Universal Biquad Filter
In this article, a novel circuit, which can function both as quadrature oscillator and universal biquad filter (lowpass, highpass and bandpass functions) is introduced. The features of the circuit are that, working as quadrature oscillator, the oscillation condition and oscillation frequency can be adjusted independently with the input bias currents: functioning as universal biquad filter, the ...

* อาจารย์ประจําสาขาวิชาเทคโนโลยีอิเล็กทรอนิกส์ คณะเทคโนโลยีอุตสาหกรรม มหาวิทยาลัยราชภัฏสวนสุนันทา AbstractThis article presents a dual-mode (voltage-mode and current-mode) universal biquadratic filter performing completely standard functions: low-pass, high-pass, band-pass, band-reject and all-pass functions, based on current controlled current conveyor transconductance amplifier (CCCCTA). The fe...
متن کاملCurrent-mode universal filter and quadrature oscillator using CDTAs
A current differencing transconductance amplifier (CDTA)-based multiple-input single-output (MISO) currentmode universal filter and a quadrature oscillator (QO) are presented in this paper. The same circuit is used in the filter and oscillator, which only consists of 2 CDTAs and 2 capacitors. The universal filter can realize low-pass, high-pass, band-pass, band-stop, and all-pass biquad filter ...
متن کاملCascadable Current-Mode Biquad Filter and Quadrature Oscillator Using DO-CCCIIs and OTA
This article introduces a circuit which can function both as a quadrature oscillator and as a universal biquad filter (lowpass, highpass, bandpass). When the circuit functions as a universal biquad filter, the quality factor and pole frequency can be tuned orthogonally via the input bias currents. When it functions as a quadrature oscillator, the oscillation condition and oscillation frequency ...
متن کاملElectronically Tunable Voltage-Mode Biquad Filter/Oscillator Based On CCCCTAs
In this paper, a circuit employing current controlled current conveyor trans-conductance amplifiers (CCCCTAs) as active element is proposed which can function both as biquad filter and oscillator. It uses two CCCCTAs and two capacitors. As a biquad filter it can realizes all the standard filtering functions (low pass, band pass, high pass, band reject and all pass) in voltage-mode and provides ...
