TLDR
Experimental results on gyration resistance, input impedance and resonant-circuit Q factor show excellent agreement with theory.Abstract:
An integrated gyrator is described. The device uses 1 diode, 12 resistors and 9 transistors, two of which are lateral p-n-p. Experimental results on gyration resistance, input impedance and resonant-circuit Q factor show excellent agreement with theory.read more

Realisation of gyrators using operational amplifiers, and their use in RC-active-network synthesis
TL;DR: The realisation of negative-impedance convertors and invertors using the bridge-type circuit using the nullor to infinite-gain controlled sources is briefly surveyed and a relevant theorem concerning passivity is proved.
