  5. 3. Monolithic Integrated Oscillators - Phase Noise Analysis and Inductor Modeling

    Author : Niklas Troedsson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monolithic inductor; Monolithic integrated oscillator; CMOS; Bluetooth; low voltage; voltage controlled oscillator; Elektronik och elektroteknik; Electronics and Electrical technology; inductor modeling; phase noise analysis; quadrature voltage controlled oscillator;

    Abstract : This doctoral dissertation studies voltage controlled oscillators (VCOs) that operate at low supply voltages. Due to smaller transistor sizes and lower supply voltage ratings with every new CMOS technology, voltage headroom is diminishing. READ MORE

  6. 4. Resitive FET Mixers

    Author : Klas Yhland; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis presents theory, device models and circuits related to resistive FET mixers: A wave analysis for resistive mixers The analysis gives an intuitive estimate of resistive mixer performance when most parameters are unknown. It is based on the assumption that all mixing terms generated in the mixer are terminated with the same impedance. READ MORE
