Methods for generating macromodels for analog functional blocks, as reported in literature, are of limited use in general circuit simulation due to either accuracy or efficiency problems. In this paper we propose a new approach to model the behavior of nonlinear analog functional blocks which produces application specific simulation models of adjustable accuracy. Experimental results are presented for an operational amplifier and art active RC-filter operating in large signal, nonlinear domain. The outlined methodology results in an increase of the simulation speed by at least one order of magnitude and opens an opportunity of system-level simulation of complex analog modules.
