ONE-DAY WORKSHOP ON
"NEXT GENERATION OPTIMIZATION METHODOLOGIES
FOR WIRELESS AND MICROWAVE CIRCUIT DESIGN"

Monday, June 28, 1999, McMaster University, Room JHE A114, 08:30-18:00
        Refreshments and lunch will be provided.

Abstract

We present new research results in optimization technology for RF, wireless and microwave circuit design, integrating electromagnetic (EM) simulations. A tutorial review as well as new research directions and algorithms in Aggressive Space Mapping (ASM) optimization are presented. Applications exploit commercial EM simulators such as Sonnet and HP HFSS: waveguide structures, microstrip filters, patch antennas, circuit decomposition techniques, mixed EM/circuit structures and signal integrity optimization of VLSI packages and interconnects.

We focus on two exciting device modeling concepts: modeling through Artificial Neural Network (ANN) technology and modeling through Space Mapping (SM) technology. These concepts have recently been merged into a variety of Space Mapping based neuromodeling strategies.

We discuss the neural network paradigm for high-frequency device modeling and circuit design. We address the development process for RF/microwave neural models. We review new directions in model development for RF/microwave components and devices utilizing ANNs and SM. Various ANN and SM based ANN models can be developed through NeuroModeler, the world's first software for neural based device modeling and circuit design. The gap between neural modeling and circuit simulation and optimization is also addressed. The gap may be bridged by plugging trained neural models into circuit simulators such as HSpice and HP ADS through NeuroSpice, a macro-processor for HSpice, and NeuroADS, a plug-in module for HP ADS. Examples include EM simulations, filters, transmission-line networks, transistor device models, etc.
