Hi,(adsbygoogle = window.adsbygoogle || []).push({});

i have this gyrator circuit that is equivalent to an inductor of 11.11mH and im required to show that if the opamps are ideal and assuming that the circuit is stable that

Zin = (Z1*Z3*Z5) / (Z2*Z4)

ive got for an ideal opamp that i+ = i- = 0 and that Aol = infinity

the ciruit is posted below..

any assistance would be greatly appreciated in proving Zin
