Design, Fabrication, and Comparative Study of Electronically Tunable Active Filters
Active and Passive Electronic Components, 1995 The Kerwin-Huelsman Newcomb (KHN) biquad is the natural choice for use as a ‘universal’ filter building block out of the several existing 3-amplifier biquadratic filter sections based on the two integrator loop or state variable realization of 2nd order ...

Active-phase-compensated biquadratic highpass filter
Electronics Letters, 1982 A new three-amplifier active-phase-compensated biquadratic highpass filter is presented. It is shown that for the matched amplifiers the circuit exhibits a stable Q-factor and, unlike the Akerberg and Mossberg highpass circuit, feedforward paths are not required.

Synthesis of Cascadable DDCC-Based Universal Filter Using NAM
Applied Sciences, 2015 A novel systematic approach for synthesizing DDCC-based voltage-mode biquadratic universal filters is proposed. The DDCCs are described by infinity-variables’ models of nullor-mirror elements which can be used in the nodal admittance matrix expansion ...
