Abstract
This paper presents a Computer Aided Synthesis and Sensitivity Analysis Tool (CASSAT) for the realization of a network function matrix and to study the sensitivity of the realized network. The development of the CASSAT is based on the state-variable approach, the reactance extraction principle and the graph theory. The CASSAT realizes any real rational network function T(s), of order q x p as an active RC-multiport network and also facilitates the study of the sensitivity of the realized network. The network is realized as an interconnection of an n-port grounded capacitor sub-network, N
c
, a (p+n)-port grounded resistive sub-network, N
R
and at the most (p+2n) inverting grounded voltage amplifier, where n equals the degree of T(s). All the capacitors and ports of the realized network share the common terminal, which is particularly attractive from the point of view of Integrated Circuit (IC) fabrication.
