Expert system issues related to monolithic microwave integrated circuit design G. Parks, D. Linton, M. Brennan, J.A.C. Stewart, V.F. Fusco Microwave Research Group, Department of Electrical and Electronic Engineering, The Queen's University of Belfast, ABSTRACT Artificial Intelligence (AI) techniques are applied to develop a framework for the design and layout of MMIC circuits. This framework addresses key aspects of the design process, from circuit specification and initial design decisions through to final layout and preparation of the circuit for fabrication. A number of knowledge-based systems are incorporated into the framework to assist in specific design areas, with amplifier design chosen to demonstrate the principles employed. INTRODUCTION Monolithic Microwave Integrated Circuits (MMICs), which are essentially microwave ASICs, are emerging as key elements in high frequency electronic systems. They are ideal where high speeds and miniature size are required and a
