Recent advances in high density low cost RF and microwave three dimensional
integration technologies using LTCC(Low Temperature Cofired Ceramics),
laminate and other multilayer hybrid and integrated circuits have increased interest
in the design of embedded passive components such as inductors, capacitors and
filters. The purpose of this study is to...
Power reduction can be achieved at many different levels, such as architecture, algorithm, logic, and transistor levels in circuit design. This thesis focuses on low power scheduling at the algorithm level. We present a latency-constrained scheduling and a latency and resource constrained scheduling, which minimize power consumption for the resources...
This thesis will examine the model and design technique of a self-contained analog
CMOS Phase-Locked Loop. This system has an adaptable filter and demodulator for an
oscillating frequency of up to 1000 KHz and it is programmable by means of an external
resistor and capacitor. The first topic to be...
Minimizing the dynamic power consumption of a circuit is becoming a more and more important issue for digital circuit design in the age of portable electronics. Among all the arithmetic circuits, addition is the most fundamental operation. Therefore, designing low power adder is an important and necessary research area.

A new circuit technique called Folded Source Coupled Logic (FSCL) has been developed
to implement the digital section of mixed-signal IC applications. This FSCL circuit technique
offers the advantage of low overlap current spikes during the switching transitions
of conventional CMOS gates. This overlap current spike has become one of...
In recent years, the rapidly growth of CMOS technology has evolved towards submicron and deep-submicron features. Due to smaller device sizes, and significant demand for low-power designs, the maximum allowable power supply voltage is restricted. So far, two solutions; clock boosting and switched opamp schemes have been proposed. The material...
To realize pipelined ADCs in deep-submicron processes, low voltage techniques
must be developed to work around problems created by limited supply voltages such as
the floating switch dead zone, reduced SNR, and reduced OpAmp performance.
This thesis analyzes standard and low voltage design issues for pipelined ADCs
and proposes a...
Spiral inductors are a key component of mixed-signal and analog integrated circuits (IC's). Such circuits are often fabricated using silicon-based technology, owing to the inherent low-cost and high volume production aspects. However, semiconducting substrate materials such as silicon can have adverse effects on spiral inductor performance due to the lossy...
