By Kelvin Yuk and Jorge Campos Written: June 7, 2002 Even though research on Silicon-on-Insulator (SOI) devices has proven it to be the next technology that will significantly improve the performance of digital integrated circuits, many skeptics have
Kelvin Yuk EEC282 Akella June 4, 2002 I. Introduction What is the problem? The problem is dealing with a high-level description of a system and finding an efficient way of co-synthesizing that system into hardware and software such that performance
By Kelvin Yuk, Claudia Wong, G. R. Branner Originally appears: European Microwave Integrated Circuits Conference., pp. 612-615, Sept 2010. Abstract An active microwave frequency tripler using an AlGaN/GaN HEMT device is developed. This is the first
Microwave frequency multipliers provide a high performance means of generating microwave and millimeter-wave signals in a wide variety of communications and radar systems. The advances in active microwave frequency multipliers due to improvements in
As reduced order modeling of large scale systems by using Pade approximation has become an important part of improving the computation speed of circuit simulation, more methods are being explored. Pade approximation by moment matching (AWE)
Using micro-scale fabrication and high voltage technologies, a fluid analysis system based on the transportation of fluid droplets by dielectrophoresis (DEP) can be developed. This thesis describes the development of a two-dimensional high voltage
By Kelvin Yuk and Chi Ho Yue EEC282 June 14, 2002 Introduction The purpose of this project is to explore details and benefits of co-design. We choose to implement the 1024-Point FFT for its applications in signal processing and communication. The
