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

    Detta är en avhandling från Chalmers University of Technology

    Författare :Roger Malmberg; Chalmers tekniska högskola.; Chalmers University of Technology.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik; Electronics; analog design; circuit synthesis; transistor model; bipolar transistor; field-effect transistor; teaching method; episteme; techne; phronesis;

    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
