A method for computer-aided noise analysis of microwave circuits described by the nodal admittance matrix is discussed. Algorithms for the computation of both the noise figure and the four noise parameters of a circuit with any topology are presented. The method and the algorithms are compatible with existing CAD software based on a nodal admittance matrix formalism. Their direct implementation into computer-aided microwave simulation and optimisation programs should significantly increase their power and computational efficiency
