Probabilistic design of integrated circuits with correlated input parameters

This paper presents an application of advanced first-order second-moment (AFOSM) reliability method to probabilistic design of integrated circuits with correlated parameters. The method avoids the transformation to the space of uncorrelated parameters and provides a conservative estimate of the yield. Optimal nominal values are found such that the cost of tolerances is minimized while the desired yield is achieved. Numerical results are presented for a switched capacitor filter and verified by Monte Carlo simulation.
