Liquid cooled, laminar microchannel heat sinks were
earlier proposed by Tuckerman for cooling high heat
generating integrated circuits and high power microwave
generation systems using photoconductive switches. A
method of computationally analyzing the heat sinks is
presented which produces the desired temperature and
velocity distributions within the heat sinks. The...
An experimental study of thermally actuated pumping of a single-phase, single-component fluid is presented in the context of thermal management of a heat source. The prominent feature of this pumping method is that the very heat that is to be removed from the heat source causes a net fluid motion....
The purpose of the thesis is to design, construct,
program, and test an automatic integrated circuit test
system. The class of integrated circuits tested was restricted
to digital integrated circuits. The general concept
of testing a digital integrated circuit is based on
the truth table of that circuit. A combination...
The object of this work was to design and fabricate an integrated circuit using Integrated Injection Logic. Integrated Injection Logic (I[superscript 2] L) is a relatively new field and has many inherent advantages. These have been exploited in this work. Logic for the desired functions was designed and implemented in...
A short-circuit-protected line-driver circuit is
particularly adapted for use in a CMOS differential line-driver
system, where one line-driver circuit provides a
true output signal, and another line-driver circuit
provides a complementary false output signal. A short-circuit
is sensed by measuring current through a secondary
pull-up transistor, and disabling a primary...
The electrical performance of on-chip interconnects has become a limiting factor to the performance of modern integrated circuits including RFICs, mixed-signal circuits, as well as high-speed VLSI circuits due to increasing operating frequencies, chip areas, and integration densities. It is advantageous to have fast and accurate closed-form expressions for the...
The electrical behavior of on-chip interconnects has become a dominant factor in silicon-based high speed, RF, and mixed-signal integrated circuits. In particular, the frequency-dependent loss mechanisms in heavily-doped silicon substrates can have a large influence on the transmission characteristics of on-chip interconnects. To optimize the performance of the integrated circuit,...
Energy consumption is one of the primary bottlenecks to both large and small scale modern compute platforms. Reducing the operating voltage of digital circuits to voltages where the supply voltage is near or below the threshold of the transistors has recently gained attention as a method to reduce the energy...
The purpose of this study is to develop experimental techniques to
characterize typical interconnect discontinuities, including bends, steps, T
junctions, vias and pads, which are the most commonly encountered
interconnections in high speed digital integrated circuits, hybrid and
monolithic microwave circuits and electronic packages. The time domain
reflection response of...
The design of high-performance, high-speed clock generation and distribution becomes challenging in terms of phase noise, jitter and power consumption, due to the fast development of communication and computing systems. Injection locking is a promising clocking technique since it can significantly improve the energy efficiency, suppress the phase noise of...
