Automatized synthesis of microwave monolitic integrated circuits with spatial and astronomy applications

Objectif

In designing MMICs, the hardest problem is to select MMIC's schematic and topology to satisfy performance specifications. This task needs very qualified designers that know electronics, microwaves and technology. The MMIC design is now based on the multiple simulation and optimization of different circuit variants, such the process is very labor- and time-consuming and may lead to non-optimal solutions. This project focuses on investigating and developing methods and software for the direct synthesis of passive and active MMICs from circuit requirements. The project will be based on the new high-frequency network synthesis approaches. The methods and software developed will allow the automatic or interactive determination of MMIC's schematic and topology directly from requirements using exact models of MMIC elements. For implementing the proposed approach to MMIC design, fast MMIC element models will be constructed for specific MMIC production processes. It is planned to build fast polynomial and neuro-network models firstly for GaAs OMMIC ED02AH process and then for another GaAs, InP, SiGe or CMOS European processes that will be selected by partner teams. Within this project, it is supposed to implemented several tools for interactive and automatic synthesis of MMIC passive and active microwave circuits: LOCUS, a tool for the "visual" design of passive matching/compensated networks, GENESYN, a GA-based tool for the synthesis of matching networks, and GENEAMP, a tool for the automatic synthesis of transistor amplifiers using GAs. Also, it is planned to develop two additional software tools: SHIFTER for designing phase shifters, and IMCON for designing negative impedance converters with application to microwave active filters. It is planned to integrate MMIC synthesis tools in such the popular simulators as Microwave Office and ADS. This task supposes the careful estimation and validation of techniques, software tools, and MMIC element models developed. For this, the design and implementation of several extreme-quality MMICs with using these techniques and tools (such as low-noise and power amplifiers, phase shifters, impedance converters, and active filters) are planned. In particular, MMIC designs for spatial, astronomy and low-noise applications will include several designs with OMMIC (GaAs), NGC Indium Phosphide (InP) and WIN (GaAs). Also, as these III/V processes have difficulty meeting the cost targets and high integration density, Silicon processes will therefore be investigated with AMS and IHP (www.ihp-microelectronics.com) in a SiGe process with frequency > 200 GHz but also with UMC in a CMOS process. The designs will be based on the SOC concept integrating amplifying and filtering functions (active filters) on a single ship. In designing negative impedance converters and active filters, the specific original design techniques of XLIM group based on the "impedance profile" will be used.
