Biquadratic SC filters with small GB effects

IEEE Transactions on Circuits and Systems, 1984
The effects of proper switch phasing in SC filters to yield low gain-bandwidth (GB) product dependence is discussed. A figure of merit for comparing GB effects in SC networks based upon the topology dependent effective GB matrices has been introduced.

Active filter realization of biquadratic transfer function

International Journal of Electronics, 1974
The realization of quadratic transfer functions by an active band-pass filter is described. The hybrid-integrated circuit used consists of a three-terminal passive network, connected to a high-gain inverting amplifier. A design procedure for minimizing the gain–sensitivity product is given.

Optimum configurations for single-amplifier biquadratic filters

IEEE Transactions on Circuits and Systems, 1980
Two new biquad circuits based on the Sallen-Key positive feedback structure are introduced and shown to be capable of realizing all possible second-order filter functions. The pole design equations and pole sensitivities are identical to those of the Deliyannis bandpass circuit which is the basis for the Friend biquad.

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 ...

A MOSFET-only continuous-time biquadratic filter

38th Midwest Symposium on Circuits and Systems. Proceedings, 2002
A MOSFET-only filter structure is described which employs an amplifier-regulated cascode structure to realize both conductance and transconductance, while the required capacitors are realized by MOSFET gate capacitance. The filter configuration is such that both MOSFET capacitors and MOSFET resistors are always biased in the triode region, so that the ...

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.

Synthesis of biquadratic filters from current conveyors

Electronics and Communications in Japan (Part II: Electronics), 1993
AbstractThis paper describes a circuit configuration for a biquad filter which utilizes the second‐generation current conveyors (CC II) and is capable of synthesizing an arbitrary second‐order transfer function.The circuit is composed of a subblock circuit with two positive CC IIs and a differential input circuit with two positive CC IIs.The subblock ...

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 ...

An approach to the sensitivity and statistical variability of biquadratic filters

IEEE Transactions on Circuit Theory, 1973
In attempting to predict the behavior of a filter during and at the end of its life, one is led to the study of sensitivity and then one must compare worst-case and expected results. This paper shows that sensitivity can be expressed as a sum of terms, where each term is the product of two sensitivity functions.

Fault simulation and testing of an OTA biquadratic filter

Proceedings of ISCAS'95 - International Symposium on Circuits and Systems, 2002
We examine the testing and fault simulation of an analog operational transconductance amplifier (OTA) biquadratic filter. Catastrophic as well as parametric deviation faults are considered. We determine if the simulated faults are detectable by comparing the output voltage from the fault-free case with each of the faulty cases.
