The paper is a study of (i) the realization of the gyrator,
(ii) active filter synthesis using gyrator.
Several realization methods of the gyrator are summarized.
A practical gyrator composed of two operational amplifiers was built
and tested. The experimental results are shown. Two RC-gyrator
synthesis techniques are derived and discussed. One method is to
replace the inductors in a conventional LC filter with gyrators and
capacitors. The other method is the application of Calahan's optimum
polynomial decomposition to the synthesis procedure. The
sensitivity of the two synthesis techniques are compared and discussed.
A practical active filter was synthesized by the second
method. The experimental results are shown.
