Effective optimization of integrated circuits with embedded passive modules by applying semisymbolic LCS AC analysis method

Abstract

Purpose -The purpose of this paper is to present a new method of optimization of electronic integrated circuits (IC) with imbedded passive modules (PM). The reported method constitutes an attempt to streamline the optimization process in the AC electrical model stage of the RF Microsystems design. Design/methodology/approach -In this method, the PM are described in symbolic form while the IC blocks remain described numerically. Whole PM can be represented as some sequence of expressions containing crucial model parameters, nominal and parasitic, which are first precompiled and next, merged automatically with the main program. Findings -The input data can be updated online according to the user's desiderata. Further, the system offers the possibility to optimize PM in diverse circumstances as well as using different technologies, and including parasitic effects. Originality/value -Usage of the semi-symbolic method for IC with embedded PM optimization based on large-change sensitivity AC analysis method, which appears to be a very efficient and flexible approach to solving such problems.
