Class AB gyrator-based active inductor

In this paper a new approach for the design of class AB active inductors is proposed. Several active solutions have been presented in the literature for replacing spiral inductors with active solutions, but class AB operation is something neglected in the literature. The proposed solution shows an easy implementation of equivalent inductors with improved characteristics of linearity and reduced losses. For demonstrative purposes the circuit has been fabricated and tested showing a series resistance of 16mΩ at 1.92GHz for an equivalent inductance of 1nH. The total power consumption is 2mW, making this solution suitable for ICs and wireless applications.
