Introducing Suspendance Analysis

Suspendance analysis is based on determinant expansion and is an effective tool for calculating node admittances. The node admittance is equal to the ratio of the suspendance obtained when the node is open to the suspendance obtained when the node is shorted. Suspendance is expressed in terms of circuit admittances and transadmittances and is calculated by shorting passive circuit components based on minimum expansion algorithm to yield compact and accurate results. Only certain passive components are shorted one at a time and multiplied by the remaining circuit suspendance. Admittances of previously shorted components are set to zero in succeeding calculations. The overall suspendance is calculated by summing contributions of shorted passive components and cross coupled voltage controlled current sources.
