The multiphase leisure experience looks at the experience as a five phase process that includes anticipation, travel to, onsite behavior, travel from, and recollection. This continuum depicts a dynamic experience, one that evolves and matures across the five phases. The purpose of this study is to take this model and apply it to sport events. Understanding sport events as a multiphase experienc...

Design and Analysis of Multiphase DC-DC Converters with Coupled Inductors. (May 2007) Meng Shi, B.Eng., Shanghai Jiao Tong University, China Chair of Advisory Committee: Dr. Prasad Enjeti In this thesis, coupled inductors have been applied to multiphase DC-DC converters. Detailed analysis has been done to investigate the benefits of directly coupled inductors and inversely coupled inductors, co...

Wireless applications are pushing the required phase noise in integrated oscillators to ever lower levels. Integrated oscillator circuits published so far use tuning inductors that are either fully integrated, partly integrated, or discrete, with quality factors spanning a large range. However, lacking a clear understanding of the physical processes of phase noise, it is difficult to compare th...

The main effort in oscillator phase noise calculation and macromodeling lies in computing a vector function called the perturbation projection vector (PPV). Current techniques for PPV calculation use time-domain numerics to generate the system’s monodromy matrix, followed by full or partial eigenanalysis. We present superior methods that find the PPV using only a single linear solution of the o...

Generally, bipolar transistors have better performance than MOS transistors if higher transconductances for the same operating point or higher transition frequencies are required. On the other hand, compared to MOS transistors, bipolar transistors often have limited use in the design of VCO’s, due to a limited voltage swing across the resonator and therefore limited phase-noise performance. How...

The Casimir effect at finite temperature is investigated for a dilute dielectric ball; i.e., the relevant internal and free energies are calculated. The starting point in this study is a rigorous general expression for the internal energy of a system of noninteracting oscillators in terms of the sum over the Matsubara frequencies. Summation over the angular momentum values is accomplished in a ...

Based on the requirement of squeezed state generation, we build the phase relationship between two electronic local oscillators for the cavity- and phase-locking branches, and a 2-way 90° power splitter is adopted to satisfy the phase relationship simultaneously, which greatly simplifies the experimental setup and adjusting process. A LC parallel resonant circuit, which is composed by the inher...

The fact that Chua's circuit can be physically decomposed into a sinusoidal oscillator coupled to an active voltage-controlled nonlinear resistor is demonstrated. The sinusoidal oscillator is the beating heart of Chua's circuit and many novel implementations can be obtained by using di!erent sinusoidal oscillator engines. In particular, inductorless realizations can be derived not by replacing ...

MOS varactors are used extensively as tunable elements in the tank circuits of RF voltage-controlled oscillators (VCOs) based on submicrometer CMOS technologies. MOS varactor topologies include conventional D=S=B connected, inversion-mode (I-MOS), and accumulation-mode (A-MOS) structures. When incorporated into the VCO tank circuit, the large-signal swing of the VCO output oscillation modulates...
