TLDR
In this paper, two active RC networks are presented for the realisation of a second-order all-pass function, each of which uses one differential-input operational amplifier and two RC networks.Abstract:
Two active networks are presented which are suitable for the realisation of a second-order allpass function. Each uses one differential-input operational amplifier and RC networks. The realisation is achieved to within a constant multiplier always smaller than unity.read more

Generation and classification of single amplifier filters
TL;DR: In this article, a unified approach for generating configurations for circuits containing one operational amplifier together with RC elements and capable of realizing a general second-order voltage transfer function is presented, which leads to various single amplifier biquads with the known circuits, as well as some new ones obtained as special cases.

Optimization of Negative-Impedance Conversion Methods of Active RC Synthesis
TL;DR: In this paper, the problem of decomposing a polynomial with real coefficients into the differences of two polynomials with negative real zeros such that the latter polynominals have coefficients which are as small as possible is addressed.
