The step size T should be such that is continuous at i.e.
In the backward step, the sensitivity at the

lation. Once these matrices and vectors are known, the time domain
sensitivity at time points of an equal interval can be obtained efficiently.
5. Statistical Analysis
5.1 Introduction
Sensitivity analysis is not capable of analyzing the joint effect of the
variation of multiple circuit parameters, especially when correlation ex-
ists. In addition, the results obtained are only valid at the nominal
value of circuit parameters and may not be valid at other values of
