Statistical analysis of nonlinear current-mode circuits

Abstract

This paper presents an efficient statistical analysis method for nonlinear current-mode circuits. The method is based on Volterra functional series representation of nonlinear systems and piecewise linear interpolation. The mean and variance of the response of nonlinear current-mode circuits with multiple nonlinear elements are computed at equi-distance points of time. The method presented in this paper has been implemented in a computer program. A second-generation current-mode memory cell is analyzed and the results are presented, together with those from Monte Carlo simulation.
