Current-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 کاملResistorless Current-mode Quadrature Sinusoidal Oscillator Using CDTAs
A circuit technique for realizing a current-mode quadrature sinusoidal oscillator using current differencing transconductance amplifiers (CDTAs) as active components is presented in this paper. The proposed circuit employing only three CDTAs and two grounded capacitors can provide two quadrature sinusoidal current outputs with 90 phase difference. The oscillation condition and the oscillation f...
متن کاملCurrent-Mode Resistorless SIMO Universal Filter and Four-Phase Quadrature Oscillator
In this paper, a new CMOS current-mode single input and multi-outputs (SIMO) universal filter and quadrature oscillator with a similar circuit are proposed. The circuits only consist of three Current differencing transconductance amplifiers (CDTA) and two grounded capacitors, which are resistorless, and they are suitable for monolithic integration. The universal filter uses minimum CDTAs and pa...

متن کاملHigh input impedance voltage-mode universal filter and its modification as quadrature oscillator using VDDDAs
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 frequency and quality factor. The proposed filter simultaneously provides five filter responses: low-pass (LP), high-pass (HP), band-reject (BR), all-pass (AP) and band-pass...
