System optimization studies related to stator design and AC/AC converter selection for brushless doubly-fed machines

Creator:: Bhowmik, Shibashis
Abstract:: The advent of superior power semiconductor devices and converter topologies has renewed interest in ac drive systems. Although considerable research efforts have gone into improving power electronic converter devices and topologies, very little has been reported on the overall performance optimization of induction machine drive systems. The report of the...

Design of a 1.8-V 14-bit [delta] - [sigma] A/D converter with 8X oversampling and 4 MHz Nyquist output rate

Creator:: Jiang, Ruoxin
Abstract:: In this dissertation, a new Δ∑ A/D converter is presented that is ideally suited for communication applications. It is based on a single-loop single-stage structure, which can realize a high maximum out-of-band quantization noise gain while maintaining stable operation and thus achieve 14-bit resolution at 8 times oversampling. A fifth-order...

Design techniques for low-voltage analog-to-digital converter

Creator:: Chang, Dong-Young
Abstract:: Continuous process scale-down and emerging markets for low-power/low-voltage mobile systems call for low-voltage analog integrated circuits. Switched-capacitor circuits are the building blocks for analog signal processing and will encounter severe overdrive problems when operating at low-voltage conditions. There are several well-known techniques to bypass the problem. These approaches include: (1)...

Low voltage switched capacitor circuits for lowpass and bandpass [delta sigma] converters

Creator:: Keskin, Mustafa
Abstract:: The most accurate method for performing analog signal processing in MOS (metal-oxide-semiconductor) integrated circuits is through the use of switched-capacitor circuits. A switched-capacitor circuit operates as a discrete-time signal processor. These circuits have been used in a variety of applications, such as filters, gain stages, voltage-controlled oscillators, and modulators. A...

Design of high-speed summing circuitry and comparator for adaptive parallel multi-level decision feedback equalization

Creator:: Gao, Hairong
Abstract:: Multi-level decision feedback equalization (MDFE) is an effective sampled signal processing technique to remove inter-symbol interference (ISI) from disk read-back signals. Parallelism which doubles the symbol rate can be realized by utilizing the characteristic of channel response and decision feedback equalization algorithm. A mixed-signal IC implementation has been chosen for...
