Sammanfattning : The thesis presents two major concerns in the design of low phase-noise MMIC VCOs; the active device model and the simulation tool. Besides, several design techniques to improve VCO tuning range and phase noise are investigated. The VCOs designed in this work are implemented in InGaP/GaAs HBT technology. LÄS MER
