2. 6. CMOS High Frequency Circuits for Spin Torque Oscillator Technology

   Author : Tingsu Chen; Ana Rusu; Jerzy Dabrowski; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave integrated circuit; CMOS; spin torque oscillator; Balun-LNA; wideband amplifier; on-chip bias-tee; multi-standard multi-band radios;

   Abstract : Spin torque oscillator (STO) technology has a unique blend of features, including but not limited to octave tunability, GHz operating frequency, and nanoscaled size, which makes it highly suitable for microwave and radar applications. This thesis studies the fundamentals of STOs, utilizes the state-of-art STO's advantages, and proposes two STO-based microwave systems targeting its microwave applications and measurement setup, respectively.

4. 7. Spin Torque Oscillator Modeling, CMOS Design and STO-CMOS Integration

   Author : Tingsu Chen; Ana Rusu; Atila Alvandpour; KTH; []
   Keywords : 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;

   Abstract : 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.

5. 8. Microwave CMOS LNAs and VCOs - Using Passives On-Chip, Above Chip, and Off-Chip

   Author : Lars Aspemyr; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VCO; LNA; CMOS; Wafer-Level-Packaging; Ferro-electric varactor; System-on-Package;

   Abstract : The performance of LNAs and VCOs is of large importance to the complete wireless communications system. To achieve sufficient performance in microwave applications, LNAs and VCOs have therefore up to now mostly been manufactured in advanced and expensive semiconductor technologies. READ MORE

6. 9. Integrated Variable-Gain and CMOS Millimeter-Wave Amplifiers

   Author : Mohammad Anowar Masud; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LNA; MMIC; FinFET; CMOS; HEMT; GaAs; WLP; VGA; BCB;

   Abstract : Variable Gain Amplifier finds extensive use in the high frequency demonstrators specially those operating in the millimeter-wave regions and beyond where the incoming RF signal level can have wide variations. To maintain a constant signal level an IF VGA has been designed that can offer a dynamic variation of gain as much as 45 dB together with a high maximum gain and a low noise figure. READ MORE
