A linear active nonreciprocal n-port is defined to be stable if the port currents are zero under all passive terminations. In this paper the stability of the prescribed nonreciprocal n-port is ascertained by finding a reciprocal n-port having identical stability characterizations. Compact stability criteria have been obtained for a general class of nonreciprocal n-port with its prescribed nXn impedance matrix in the tridiagonal form of a matrix of Jacobi.
The necessary and sufficient condition for the stability of an n-port can also be formulated in terms of its driving-point impedance at each of its ports when all the other (n --1) ports are terminated in arbitrary passive impedances. By using the impedance transformation property of the linear n-port and an iterative procedure of the bilinear transformation, stability criterion for a general nonreciprocal n-port can be obtained.

## Abstract A set of necessary and sufficient conditions is stated and proved for the absolute stability (under any passive terminations), in the βbiboβ sense, of a linear __n__βport characterized by its openβcircuit impedance matrix. A more explicit set of such conditions is derived for the specia
Based on the two-port describing function characterization, frequency domain stability conditions are derived for non-linear two-port amplifiers. The conditions are applied to the case of a tuned transistor amplifier with saturated class-C type transfer characteristic. The theoretical considerations
