A synthetic network using current conveyors of the open-circuit impedance matrix of a linear time-invariant multiport

Abstract

Previous research appearing in the literature required that all the realizable z parameters of the open-circuit impedance matrix of a linear time-invariant multiport network must be real, rational, stable functions. Although different z parameters could be selected independently without necessarily to having common poles, this also required that all the z parameters be minimum phase. A synthetic network using second-generation current conveyors (CCIIs), third-generation current conveyors (CCIIIs) and differential difference current conveyors (DDCCs) is proposed here, with each transfer impedance parameter being either minimum or nonminimum phase. Additionally, it can be designed automatically by computers since the current conveyor circuits, the transfer functions and numerical methods are available.
