Low-Noise Mixing Circuits in CMOS Microwave Integrated Circuits
In this thesis, three low-noise active mixing circuits are presented in CMOS technology. Mixers can be found at the front-end of almost every communication systems. However, despite many advantages the active mixers have, ...
Subharmonic Mixers in CMOS Microwave Integrated Circuits
This thesis explores the design and applications of subharmonic mixers in CMOS microwave integrated circuits. First, a 2x down-converting subharmonic mixer is demonstrated with a measured conversion gain of 8 dB using a ...
Novel Digital Controller for Multi Full-Bridge DC/DC Converter
Distributed generation that utilizes 5-10kW Solid Oxide Fuel Cells requires power electronics to optimize the overall system efficiency while reducing the cost. The Adaptive Energy Zero-Voltage-Switching Phase-Shift-Modulated ...
Link Adaptation for Energy Constrained Networks
Relay terminals are often used in tandem in sensor networks to lessen nodal communication burden. In this light we investigate the problem of power allocation amongst nodes in a relay network in order to maximize the overall ...
MOSFET Current Source Gate Drivers, Switching Loss Modeling and Frequency Dithering Control for MHz Switching Frequency DC-DC Converters
The power density of a switching converter is dependent on the size of the power circuit components. Converters are operated in the hundreds of kHz to achieve high power density since the size of the converter reactive ...
