Microwave Planer-Probe Traveling-Wave Power Dividing-Combining: Author: Dickman, Edward John; Date: 2005-12-15; Program: Electrical Engineering; Abstract: TAs the millimeterwave and sub-millimeterwave portions of the electromagnetic spectrum are increasingly utilized, the need for greater power at those frequencies also increases. Unfortunately, as frequency is increased, the power available from a single solid-state device decreases. Thus, in many applications, the combining of power from several solid-state devices becomes necessary to have usable signal power levels. This thesis presents two such power combining approaches, whose designs are compatible with existing microfabrication techniques that may be used to produce devices operating at ...; Download File | View full details

A Planer Probe Double Ladder Waveguide for Power Combining and Dividing: Author: Oudrhiri, Mohammed Adil; Date: 2004-05-15; Program: Electrical Engineering; Abstract: This thesis presents an initial investigation of a planar probe double ladder power combiner / divider. The structure is analogous to the coaxial double ladder of Sanada, Fukui and Nogi*. The planar probe structure utilizes a series of planar transmission lines and probes to inject or receive power which is combined or divided inside a rectangular waveguide cavity. The structure was developed in a manner for its eventual implementation at W-band (75.0-110.0 GHz) frequencies and above using proven micromachining techniques. A combination of analytical modeling, transmission line analysis and fu...; Download File | View full details

Distributed Amplifier Circuit Design using a Commercial CMOS Process Technology: Author: Ross, Kyle Gene; Date: 2006-08-15; Program: Electrical Engineering; Abstract: The demand for ever increasing amounts and rates of data transmission is one of the most significant driving forces in the design of modern telecommunications systems. In response, integrated circuit (IC) designers are forced to achieve higher and higher bit rates. Increased bit rates in turn impel the IC communication systems to achieve ever larger bandwidths while maintaining stringent requirements on other design specifications such as cost, die-size and power consumption. One alternative approach to high-bandwidth design showing promise is the design of distributed integrated circuits. Dis...; Download File | View full details

On-Chip Automatic Tuning of CMOS Active Inductors for Use in Radio Frequency Integrated Circuit (RFIC) Applications: Author: Lyson, Kyle Joshua; Date: 2006-12-15; Program: Electrical Engineering; Abstract: The lack of high quality factor integrated inductors is a significant impediment to realizing high performance Radio Frequency Integrated Circuits (RFICs) within conventional digital CMOS. While passive spiral inductors continue to improve with different approaches and fabrication techniques, they tend to be large and lossy. Therefore, an accurate inductance with high quality factor and small chip area would be an extremely useful component for RFIC designers. The focus of this thesis is realizing accurate, high-quality factor inductance using an active circuit approach for implementation in R...; Download File | View full details

Process voltage temperature compensated on-chip CMOS active inductors for Wilkinson power dividing applications: Author: Bucossi, William Louis; Date: 2008-05-15; Program: Electrical Engineering; Abstract: Few academic or industry feasibility studies have been published on the implementation of Active Inductors in a standard CMOS IC process as an alternative to the physically large and typically quite lossy spiral inductors. Development efforts at the simulation level have achieved only limited success in creating an Active Inductor topology that exhibits the quality and inductive tolerance necessary for the large-scale, high-volume production common to most IC components. This thesis focuses on manufacturing and characterizing the basic component circuitry necessary for the implementation of a ...; Download File | View full details
