New switched-capacitor universal biquadratic filter
International Journal of Electronics, 1991A new switched-capacitor (SC) universal biquadratic fitter is presented. The circuit uses three operational amplifiers and can simultaneously realize lowpass, bandpass and highpass transfer functions in a single SC structure. The filter is parasitic free, requires less capacitor spread and total capacitance, and enjoys very low sensitivities.

A systematic method of generating biquadratic filter sections
International Journal of Electronics, 1974Biquadratic filter sections for use alone or as building blocks for higher-order active filters can be generated by a simple two-step synthesis technique The first step is aimed at synthesis of the poles realizing not only the polo-Q and resonant frequency, but also the type of feedback present in the circuit.

Mixed-Mode Universal Biquadratic Filter with No Need of Matching Conditions
Journal of Circuits, Systems and Computers, 2016None of the previously reported mixed-mode universal filters can achieve the following important advantage: no need of component matching conditions. This paper presents a new mixed-mode (including voltage, current, transadmittance, and transimpedance modes) universal biquadratic filter with no need of matching conditions (including no need of ...

Continuous-Time Active Filters - Biquadratic Realizations
2003In 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.
