متن کاملCCCDTAs-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 ...
متن کاملHigh output impedance current-mode multifunction filter using FTFNs
A new current-mode (CM) single input three outputs (SITO) multifunction filter topology is presented, which employs only three FTFNs or OFAs and five passive elements. From this topology, two filter circuits can be derived selecting the passive elements properly. The proposed filter realizes three filter functions simultaneously all at high impedance outputs. No component matching is required a...
متن کاملVoltage-mode Sito Multifunction Filter Using Only Two Ftfns
In this paper we present a new voltage-mode (VM) multifunction filter configuration using only two four terminal floating nullors (FTFNs) and five passive elements. The circuit with a single input and three outputs can simultaneously realise lowpass (LP), bandpass (BP) and highpass (HP) filter responses. The natural frequency ( 0 ω ) and the bandwidth ( /Q ω0 ) can be orthogonally controlled. T...
متن کاملAnalogy Fault Model for Biquad Filter by Using Vectorisation Method
In this paper a simple shortcoming model for a CMOS exchanged capacitor low pass channel is tried. The exchanged capacitor (SC) low pass channel circuit is modularized into practical macros. These useful macros incorporate OPAMP, switches and capacitors. The circuit is distinguished as flawed if the recurrence reaction of the exchange capacity does not meet the configuration detail. The sign st...
