   Author : Magnus Wiklund; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circuit synthesis; Bond graphs; Nullor; Circuit theory; Analog simulation; Circuit simulation; Multiprocessor computer; CONCISE; Parallel computation; Waveform relaxation; Thermal models; Transistor models; Electro-thermal simulation; Electro-thermal modeling; Translinear circuits; Electronics; Elektronik; Electrical engineering; Elektroteknik;

   Abstract : The main purpose of this work is to study methods to simulate electro-thermal effects in integrated circuits using CONCISE a waveform relaxation based circuit simulator. WR is a method that is suitable to run on a multi-computer with state of the art computing power. Especially CMOS VLSI circuits have been simulated successfully with WR. READ MORE

4. 2. Analog Circuit Topology Development: Practice methods for technology and teaching based on comprehensible transistor models

   Author : Roger Malmberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; episteme; analog design; circuit synthesis; field-effect transistor; teaching method; phronesis; techne; bipolar transistor; transistor model;

   Abstract : To obtain adequate knowledge for design of robust analog circuits in industry, circuit engineers gain main knowledge from own practice experience, because theory taught by universities rarely states validity limits and result spreads. Therefore, when going from university to industry, the engineers find this theory nontrustworthy and relinquish it. READ MORE

5. 3. A computer-aided approach to design of robust analog circuits

   Author : Emil Hjalmarson; Georges G.E. Gielen; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analog circuit design; computer-aided design; Electrical engineering; Elektroteknik;

   Abstract : Traditional design methods for analog circuits are based on rules-of-thumbs, experience, and trial-and-error approaches involving the use of circuit simulators. It is an unstructured process, which is time-consuming, error prone, and requires the attention of a skilled analog designer. READ MORE

   Abstract : Silicon carbide (SiC) integrated circuits (ICs) can enable the emergence of robust and reliable systems, including data acquisition and on-site control for extreme environments with high temperature and high radiation such as deep earth drilling, space and aviation, electric and hybrid vehicles, and combustion engines. In particular, SiC ICs provide significant benefit by reducing power dissipation and leakage current at temperatures above 300 °C compared to the Si counterpart. READ MORE
