Versatile current-mode active- biquadratic filter

International Journal of Electronics, 1995
A current-mode active-R biquadratic filter is realized using operational amplifiers. It is shown that the proposed circuit can realize lowpass, bandpass, highpass, bandstop and allpass transfer functions simultaneously without changing the circuit topology and elements.

Microwave, biquadratic, active-RC filter development

International Journal of RF and Microwave Computer-Aided Engineering, 1998
We present a number of computer-simulated results for a recently developed family of active-RC, microwave, biquadratic filters. These circuits are gyrator-based and contain negative second-generation current conveyors (CCII−s) realized as cascades of MMIC GaAs FETs. First, the circuit family is extended to include asymmetric band-reject filters.

Allpass biquadratic switched-capacitor filters

IEEE Transactions on Circuits and Systems, 1985
Biquadratic allpass filters are of great importance for performing phase equalization in highly selective filters such as those employed in modems or other telecommunications equipment. This paper develops and examines topologies for implementing the switched-capacitor (SC) allpass biquad including all of the sampled data effects in the design ...

SIMO Type Voltage-Mode Biquadratic Multifunction Filter

2019 6th International Conference on Signal Processing and Integrated Networks (SPIN), 2019
A new circuit of voltage-mode biquadratic multifunction filter based on fully differential second generation current conveyor (FDCCII) is introduced in this paper. It is realized using one FDCCII, three resistors and two capacitors. The filtering functions namely, low-pass, high-pass, band-pass and band-reject (LP, HP, BP and BR, respectively) are ...

Lossy-integrator biquadratic RC-active filters

IEEE Transactions on Circuits and Systems, 1977
A lossy-integrator realization of any of the common biquadratic transfer functions is presented, employing three isotopic dual-input active blocks. The principal advantage offered by the proposed canonic networks is that the intrinsically stable active blocks may be trimmed in isolation using simple gain and phase measurements made at a single ...

Single CFTA-based dual-mode biquadratic filter

2018 3rd International Conference on Control and Robotics Engineering (ICCRE), 2018
A scheme consisting of only one current follower transconductance amplifier (CFTA) and four passive components is introduced for realizing the novel dual-mode universal biquadratic filter. The introduced filter can perform either in voltage-mode or current-mode, and can realize the highpass, bandpass and lowpass filter responses simultaneously without ...

Voltage mode biquadratic filter using single OTRA

2012 IEEE 5th India International Conference on Power Electronics (IICPE), 2012
In this paper, a voltage mode (VM) biquadratic filter configuration using single Operational transresistance amplifier (OTRA) is proposed. The topology can be used to synthesize lowpass, highpass and bandpass filter functions with appropriate admittance choices.

A Generalized Biquadratic Filter with Parameter Display

IEEE Transactions on Instrumentation and Measurement, 1980
An instrument that couples a new type of biquadratic filter with a picture display capability of s-plane pole and zero locations is described. The filter design allows easily movable, continuous, and orthogonal pole-zero adjustment by the user of all possible stable combinations of biquadratic functions.

Design of Configurable gm−C Biquadratic Filter

Journal of Circuits, Systems and Computers, 2016
Design methodology of a voltage-mode programmable biquadratic filter using minimum components is proposed in this paper. Multifunction second-order filter has been implemented using two first-order filter sections. The proposed biquadratic filter has been realized with operational transconductance amplifier (OTA).

Multifunction biquadratic filters using current conveyors

IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 1997
Some novel multifunction biquadratic filters with voltage gain, each of which employs four current conveyors, two grounded capacitors, and three-five resistors, are presented. Each proposed circuit offers the following advantageous features: realization of different biquadratic filter signals from the same configuration, no requirements for component ...
