  1. 1. Reactors - Circuit Theory and Silicon Integrated Applications

    Författare :Pietro Andreani; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Filters; Delay Lines; VCOs; Inductors; Circuit Theory; Capacitors; CMOS; Electronics; Elektronik;

    Sammanfattning : This dissertation deals with reactive components in electric circuits, both as targets for a theoretical circuit analysis, and as devices implemented in silicon processes like CMOS. The frequency behavior of a general electric network is determined by the reactances (i.e. LÄS MER
