Sensitivity minimisation and partitioned transformations in active equivalent networks

Following the extension of equivalence transformations to a general class of electrical networks containing active devices such as operational amplifiers, the theory is developed to accommodate the minimisation of the sensitivity of the network response function to component variations. Theorems for passivecomponent sensitivity invariance and for updating routines applicable to the optimisation step are proved. Previous limitations imposed upon the optimisation routine by equality realisability constraints are completely eliminated by a partitioned approach. This leads to a new form of transformation. The partitioned transformation can be implemented in both discrete and continuous forms, and applied to the optimisation of component values and sensitivities in active networks
