Noise power sensitivities and noise figure minimization of two-ports with any internal topology

A theoretical foundation is presented for efficient CAD-oriented computation of first-order noise power sensitivities of networks with respect to network parameters. Application to the CAD of low-noise circuits with a minimum noise figure using efficient gradient optimization methods is envisaged. T...

Zusammenfassung:A theoretical foundation is presented for efficient CAD-oriented computation of first-order noise power sensitivities of networks with respect to network parameters. Application to the CAD of low-noise circuits with a minimum noise figure using efficient gradient optimization methods is envisaged. The approach is applicable to circuits with any internal topology composed of any number of passive linear multiports and active linear two-ports. It is based on the scattering matrix description for circuit elements and wave representation for noise.< >
