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.

Voltage Mode Single OTRA Based Biquadratic Filters

2012 Third International Conference on Computer and Communication Technology, 2012
In this paper, single operational transresistance amplifier (OTRA) based biquadratic filter configuration is proposed. The topology can be used to synthesize low pass, high pass and band pass filter functions with appropriate admittance choices. This configuration can implement filters with high quality factor which can be controlled independent of ...

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 ...

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.

REALIZATION OF SQUARE ROOT DOMAIN TOW–THOMAS BIQUADRATIC FILTER

Journal of Circuits, Systems and Computers, 2010
In this paper, a Tow–Thomas biquadratic filter designed in square root domain is proposed. The presented filter is constructed with a lossy integrator, a lossless integrator, and a summer block. To the best knowledge of the authors, the filter is the first square root domain Tow–Thomas filter in the literature. The state space synthesis method is used

Continuous-Time Active Filters - Biquadratic Realizations

2003
In this chapter, the design and performance of single-amplifier and multiple-amplifier active-RC and active-R(C) biquad circuits has been considered. Negative-feedback single-amplifier circuits have been shown to have low-Q sensitivities to passive components but large ωo and Q sensitivities to the Op Amp GB.

The analytical design of biquadratic parametric filters

[1991] IEEE Pacific Rim Conference on Communications, Computers and Signal Processing Conference Proceedings, 2002
Quadratic and biquadratic filter sections are often used in audio applications since only moderate filter Q's are required. Closed-form expressions for analog biquadratic bandpass filters meeting prescribed specifications are derived. These results are then extended to the discrete-time domain through the use of the bilinear transformation.
