Interactive Internet connection for a remote digital signal processing lab

Creator:: Ehler, Michael
Abstract:: A remote Digital Signal Processing (DSP) lab for the Internet is developed to give students the opportunity to work together online with a remotely located Digital Signal Processor (DSP). Students in different locations can work together with the DSP as if they were present in the lab. To make this...

Design Techniques for Wide-bandwidth Continuous-time Delta-sigma Modulators with Noise-shaping Quantizers

Creator:: Dey, Siladitya
Abstract:: Noise-shaping multibit quantizers in a ΔΣ modulator offer extra orders of noise shaping without increasing the loop-filter order and without compromising the stability of the modulator. This dissertation presents two new architectures for improving the overall performance of continuous-time ΔΣ modulators using noise-shaped quantizers. The first modulator architecture is motivated...

Performance enhancement techniques for low power digital phase locked loops

Creator:: Elshazly, Amr
Abstract:: Desire for low-power, high performance computing has been at core of the symbiotic union between digital circuits and CMOS scaling. While digital circuit performance improves with device scaling, analog circuits have not gained these benefits. As a result, it has become necessary to leverage increased digital circuit performance to mitigate...

Broadband modeling of on-chip transformers for silicon RFICs

Creator:: Rapolu, Kavitha
Abstract:: Magnetically coupled passive transformers are increasingly integrated on-chip for various analog and radio frequency (RF) applications including direct current (DC) isolation, impedance transformation/matching, and conversion between single-ended and differential signals. A primary motivation for the on-chip integration of transformers is the overall size reduction and reduced cost. However, the performance...

Inductors in high-performance silicon radio frequency integrated circuits : analysis, modeling, and design considerations

Creator:: Lutz, Richard D., Jr
Abstract:: 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...

Next generation analog-to-digital conversion using time-based encoding and digital synthesis techniques

Creator:: Muhlestein, Jason, Russell
Abstract:: The internet-of-things is a growing market segment which is based on an arrayof portable communication devices with high power efficiency. Advanced semiconductortechnology can easily improve their digital performance, but the samecannot be said for the analog blocks which are vital to their operation. Highperformance analog circuits continue to use conventional...

Modeling and Design of Interconnects and Passive Components for Millimeter-Wave Integrated Circuits in Silicon

Creator:: Zheng, Lei
Abstract:: For mmWave Integrated Circuit (IC) design, co-integration of passives can reduce size and power consumption, increase reliability, and reduce overall cost. However, skin and proximity effects in the metallization are aggravated at mmWave frequencies, resulting in increased attenuation and degradation of overall performance. Furthermore, tight integration of passive components (to...

Methods to improve the reliability and resiliency of near/sub-threshold digital circuits

Creator:: Crop, Joseph A.
Abstract:: 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...

Wide-bandwidth, high-resolution delta-sigma analog-to-digital converters

Creator:: Zanbaghi, Ramin
Abstract:: There is a significant need in recent mobile communication and wireless broadband systems for high-performance analog-to-digital converters (ADCs) that have wide bandwidth (BW>5-MHz) and high data rate (>100-Mbps). A delta-sigma ADC is recognized as a power-efficient ADC architecture when high resolution (>12-b) is required. This is due to several advantages...
