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

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

   Sammanfattning : 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. LÄS MER
