A study on the effects of the geometrical and physical parameters of the GaAs MMIC process on the yield of large-signal circuits is presented, Large-signal yield analysis as well as large-signal yield optimization are performed using a large-signal lumped-element MIESFET model related to MMIC process parameters, and suitable for implementation in commercial microwave CAD tools, The characterization of all the statistical variables of a large-signal circuit provides a better understanding of the yield behavior, In particular, the sensitivity of large-signal yield to MMIC process parameters is computed and the statistical behaviour of each parameter is presented by means of yield sensitivity histograms.
