   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; STO technology; microwave oscillator; analytical model; macrospin approximation; Verilog-A model; high frequency CMOS circuits; balun-LNA; STO-IC integration; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Spin torque oscillators (STOs) are microwave oscillators with an attractive blend of features, including a more-than-octave tunability, GHz operating frequencies, nanoscale size, nanosecond switching speed and full compatibility with CMOS technology. Over the past decade, STOs' physical phenomena have been explored to a greater extent, their performance has been further improved, and STOs have already shown great potential for a wide range of applications, from microwave sources and detectors to neuromorphic computing.
