Reciprocal Darlington section suitable for an integrated circuit

A reciprocal gyrator-capacitor section is proposed with reference to integrated realisations. The section, containing four grounded gyrators and four capacitors, realises any complex 2nd-order even-part zero of a driving-point admittance and reduces the degree of the admittance function by four. The element values of the section are given in the terms of the extracted transmission zero and the value of the admittance function at the extracted zero.
