Time-domain performance bound analysis of analog circuits considering process variations

In this paper, we propose a new time-domain performance bound analysis method for analog circuits considering process variations. The proposed method, called TIDBA, consists of several steps to compute the bound performances in time domain. First the performance bound in frequency domain is computed for a linearized analog circuits by an variational symbolic analysis method and the Kharitonov's functions. Then the time domain performance bound is computed via a new general-signal transient bound analysis method. The new algorithm can give transient lower bound and upper bound of the performance variations affected analog circuits accurately and reliably. Experimental results from two industry benchmark circuits show that TIDBA gives the correct bounds for the Monte Carlo analysis while it delivers one order of magnitude speedup over the Monte Carlo method.
