Design of RSD-cyclic and hybrid RSD-Cyclic/sigma-delta ADCs
Atris, Youssef H. (Wichita State University, 2007-07)In this research work two contributions to the area of analog to digital data converters have been discussed. The area of focus is the RSD-Cyclic and sigma-delta ADC. First a novel hybrid RSD-Cyclic-sigma-delta architecture ... -
Implementation performance analysis comparison for two methods of implementing a fourth-order Chebyshev type II cascode NTF delta sigma converter architecture
BhojeGowda, Prakash (Wichita State University, 2005-07)There is increasing interest in continuous-time implementations of sigma-delta modulators, especially for high-speed and low-power applications. This is primarily due to some important advantages continuous-time realizations ... -
Mapping a controller from the s-domain to z-domain using Magnitude Invariance Method (MIM).
Vadhavkar, Prathamesh R.; Watkins, John Michael; Paarmann, Larry D. (Wichita State University. Graduate School., 2007-04-27)We are presenting a new approach for mapping a continuous time controller to a discrete time controller. Methods traditionally used for this mapping include forward rectangular rule, bilinear rule and zero-pole matching. ... -
Nonlinear spectrum compression for the hearing impaired via a frequency-domain processing algorithm
Paarmann, Larry D. (IEEE, 2006-08-30)In this paper, the results of both normal-hearing, and profoundly hearing-impaired adults, tested with spectrum compressed speech via the modified chirp-z algorithm, with and without visual stimuli, are reported. Ten ...
