LSU Master's Theses
This work presents the design and implementation of CMOS LC voltage controlled oscillators. On-chip planar spiral inductors and PMOS inversion mode varactors were utilized to implement the resonator. Two voltage controlled oscillators (VCOs) were realized as a part of this work, one designed to operate at 1.1 GHz while the second at 1.8 GHz. Both VCOs were implemented in a scalable digital CMOS process, with the former in a 1.5 micron CMOS process and the latter in a 0.5 micron technology. A simulation based methodology was adopted to arrive at a simple pi model used to model the metal and …
