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 ...

New current-feedback amplifier-based universal biquadratic filter

IEEE Transactions on Instrumentation and Measurement, 1995
A new universal biquadratic filter configuration using two current feedback amplifiers (CFA's) is presented. The proposed configuration can realize the second-order lowpass, bandpass, highpass, notch and allpass filters. Both the active and passive sensitivities are no more than unity.

Universal biquadratic filter using Operational Floating Current Conveyor (OFCC)

2016 28th International Conference on Microelectronics (ICM), 2016
A universal biquadratic filter in voltage mode (VM) and current mode (CM) configuration using single Operation Floating Current Conveyor (OFCC) is presented in this paper. It realizes all standard filter functions i.e. low pass (LP), high pass (HP), band pass (BP), notch and all pass (AP) without changing circuit topology.

Universal Biquadratic Current-Mode Filter Using a Single EX-CCCII

2019 International Conference on Electrical, Electronics and Computer Engineering (UPCON), 2019
This paper present a current-mode electronically tunable biquadratic filter. A single EX-CCCII is used for designing the new circuit. Moreover two capacitors and three switches are also used. All standard second order filter responses are realized by selecting the proper input current terminals (I IN1 , I IN2 ) and switches (SW 0 , SW 1 , SW 2 ).

New CCII-based voltage-mode universal biquadratic filter

International Journal of Electronics, 1997
A new voltage-mode universal biquadratic filter configuration using two secondgeneration current conveyors (CCIIs) and four passive components is presented. The proposed configuration can realize the second-order low-pass, band-pass, high-pass, notch and all-pass transfers with unity gain. Both its active and passive sensitivities are small.
