Abstract :
A general class of current amplifier-based biquadratic filter circuits is presented which is capable of realizing arbitrary filter functions including the lowpass, highpass, and the bandpass transfer function. These realizations are derived from a class of well-known low sensitivity single amplifier biquadratic (SAB) filter circuits using the principle of adjoint networks. The salient features of the proposed current amplifier filter circuits are that they are synthesized using the same procedure circuits as their op-amp based SAB circuit counterparts, and furthermore, possess the same sensitivities to component variations as the original SAB circuits
