Effect of OTA’s major nonidealities to passive equivalent circuit model of the alternatively structured higher performance OTA-based floating inductor

In this research, the effect of two major OTA's nonidealities entitled the parasitic elements and finite opened-loop bandwidth to the passive equivalent circuit model of the alternatively structured higher performance OTA-based floating inductor which requires four OTAs i.e. 4-OTA based floating inductor, which has been found to be practically far superior to its 3-OTA counterpart, have been explored. The contributory results of this research have been found to be the derivation of the passive equivalent circuit model of the 4-OTA-based floating inductor under the effect of both major nonidealities which has been found to be applicable in the practical phenomena. The derived passive equivalent circuit model has also been found to provide a sufficient accuracy. Hence, it has been found to be a convenience tool for the design of any inductor substitution based analog/mixed signal filters.
