3D Device Simulation of SEU-Induced Charge Collection in 200 GHz SiGe HBTs

Yang, Hua (2005-12-15)

This thesis presents three dimensional device simulations of SEU (single-event upset)-induced charge collection in 200 GHz SiGe HBTs. The device was constructed and simulated using Davinci. The charge collected by each ...

Design and Optimization of Nano-scaled Silicon-Germanium Heterojunction Bipolar Transistors

Shi, Yun (2005-08-15)

In this work, we explore the design and optimization of nano-scaled SiGe HBTs. The cutoff frequency fT and the maximum oscillation frequency fmax are optimized towards Terahertz. We first start with intrinsic device designs ...

Design of 3.33GHz CML Processor Datapath

Owahid, Abdullah (2012-04-17)

Almost a decade processor speed has been stuck at operating frequency 2-3GHz due to excessive power consumption of CMOS logic gate at higher frequency whereas predicted speed at present was 10-15GHz. This leads the idea ...

Evaluating the Digital Fault Coverage for a Mixed-Signal Built-In Self-Test

Lusco, Michael (2011-11-21)

This thesis focuses on a digital Built-in Self-Test (BIST) approach to perform specification- oriented testing of the analog portion of a mixed-signal system. The BIST utilizes a direct digital synthesizer (DDS) based ...

High Frequency Noise Modeling and Microscopic Noise Simulation for SiGe HBT and RF CMOS

Cui, Yan (2006-12-15)

RF bipolar and CMOS are both important in RFIC applications. Modeling of noise provides critical information in the design of RF circuits. Unfortunately, available compact models for both RF bipolar and CMOS, are typically ...

A Low Power, Low Noise Phase Locked Loop MMIC for Ku- and X-Band Applications

Ray, Mark (2009-03-23)

This paper presents the analysis, design, simulation, and test results for a Fractional-N PLL frequency synthesizer. The synthesizer is designed to cover multiple frequency bands, require low power, and have low noise. ...

Modeling and Scaling Limitations of SiGe HBT Low-Frequency Noise and Oscillator Phase Noise

Tang, Jin (2006-08-15)

This dissertation presents modeling of SiGe HBT low-frequency noise and oscillator phase noise, and examines their limitations posed by technology scaling. A new method of extracting low-frequency noise, inverse circuit ...

Perfomance Analysis of 802.11b Networks

Paruchuri, Ravi-Chandra (2006-05-15)

Wireless local area networks (WLANs), especially those incorporating the 802.11b standard, have experienced rapid evolution and unprecedented widespread deployment during the past few years. Increasing research led to the ...

Process-Variation-Resistant Dynamic Power Optimization for VLSI Circuits

Hu, Fei (2006-05-15)

Power dissipation is an increasingly critical issue in modern VLSI design and testing. Previously, linear programming (LP) based methods have been proposed for optimization of circuits for low power dissipation. However, ...

Systematic Characterization and Modeling of Small and Large Signal Performance Of 50 - 200 Ghz SiGe HBTs

Pan, Jun (2005-08-15)

Over the last ten years, SiGe BiCMOS technology has become the leading technology in analog circuit design for both wired and wireless telecommunication applications. However, the endless pursuit for high performance is ...
