The Biquadratic Filter [A Circuit for All Seasons]

IEEE Solid-State Circuits Magazine, 2018
The biquadratic filter, also known as the "biquad," dates back to the 1960s [1]-[3] but still serves as an essential building block in analog filter design. In this article, we study this circuit's properties and design issues.

Realization of biquadratic filter by using memristor

2013 The International Conference on Technological Advances in Electrical, Electronics and Computer Engineering (TAEECE), 2013
In this study, a brief review of the memristor and its terminal equations are given. Biquadratic filter implementation with memristor is introduced. SPICE subcircuit model is presented to simulate the memristor. Gain and phase characteristics of the proposed biquadratic filter are obtained with SPICE circuit simulator.

Biquadratic universal filter based on CCDDCCTA

2016 International Conference on Microelectronics, Computing and Communications (MicroCom), 2016
A voltage mode (VM) biquadratic universal filter using a current controlled differential difference current conveyor transconductance amplifier (CCDDCCTA) is discussed. The proposed filter uses two capacitors and one CCDDCCTA block only. It has following important facets: (i) Low pass (LP), band pass (BP), high pass (HP), notch and all pass (AP ...

Design of CMOS VHF/RF Biquadratic Filters

Analog Integrated Circuits and Signal Processing, 2002
In this paper, a class of CMOS biquadratic filter suitable to work at VHF/RF frequency range is presented. The proposed circuit has a simple structure which is analyzed and designed according to a universal i>Gm-C biquad filter. Simulation and experimental results show that these filters can work in GHz range and have wide tuning range.

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).

On the restrictions of the sensitivities in single‐amplifier biquadratic active filters

International Journal of Circuit Theory and Applications, 1995
AbstractThe paper deals with the bounds on the sensitivities of the poles and the quality factor to the gain of the amplifier in biquadratic second‐order active filters. to ensure stability, the Fialkow‐Gerst conditions are taken into account. It is not possible to realize biquad filters with a better gain‐sensitivity product not obeying the derived ...

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.

Current mode biquadratic universal filter

2015 IEEE Asia Pacific Conference on Postgraduate Research in Microelectronics and Electronics (PrimeAsia), 2015
A current mode universal filter using current controlled differential difference current conveyor transconductance amplifier (CCDDCCTA) is discussed. The filter provides important and desirable features : (i) Uses only one CCDDCCTA and two capacitors, (ii) One can get low pass (LP), band pass (BP), high pass (HP), notch (NF) and all pass (AP) current ...
