This paper describes a new electronically tunable four inputs and single output voltage-mode universal biquadratic filter based on simple CMOS operational transconductance amplifiers (OTAs) and grounded capacitors. The proposed filter provides low-pass, high-pass, band-pass, band-stop and all-pass voltage responses at a high impedance input terminal, which enable easy cascadability. The circuit parameters...
A new current-mode current-controlled single-input multiple-output universal filter, which employing only three translinear current conveyors and two grounded capacitors. The proposed configuration provides lowpass, bandpass, highpass, bandstop and allpass current responses at a high output impedance terminal, which enable easy cascadability of the circuit. The circuit parameters natural frequency...
A high input impedance electronically tunable voltage-mode biquadratic filter with single input and three outputs using four simple CMOS operational transconductance amplifiers and two grounded capacitors is proposed. The proposed filter provides low-pass, band-pass and high-pass voltage responses at a high input impedance terminal, which enables easy cascadability of the voltage circuit. Also, the...
In this paper, a new single input and five outputs voltage-mode universal biquadratic filter with high-input impedance is presented. The proposed circuit employs three plus-type differential difference current conveyors, two grounded capacitors and three resistors and offers the following features: realization of all the standard filter functions, that is, high-pass, band-pass, low-pass, notch, and...
