Analytical modeling of early voltage and common emitter current gain for Si1-yGey heterojunction bipolar transistor

Fazle Rabbi (Department of Electrical and Electronic Engineering (EEE), 2012-05)

The Early voltage describes the output conductance and the load drive capability of bipolar transistors, so high Early voltage is desirable for any device. An increase in the collector–base voltage causes a greater reverse ...
Impact of intra-channel cross-phase modulation on high speed optical fiber communication system

Nitu Syed (Department of Electrical and Electronic Engineering (EEE), 2012-06)

In this thesis, analytical estimation of phase fluctuations due to intra-channel crossphase modulation (IXPM) on return-to-zero (RZ) pulse has been studied in details for both uncompensated single line transmission and ...
Modeling optical transition energies in semiconducting single wall carbon nanotubes and assignment of their chirality

Ahmed Jamal, G. R. (Department of Electrical and Electronic Engineering (EEE), 2012)

An empirical model of nearest neighbor hopping parameter (γ0) in tight binding (TB) model of single wall carbon nanotubes is proposed in order to calculate first and second optical transition energies of semiconducting ...
Method of detection and classification of nasalized vowels based on acoustic features derived from both magnitude and phase spectra

Shamima Najnin (Department of Electrical and Electronic Engineering (EEE), 2012-07)

The performance of the detection and classi cation of nasalized vowels from the mixture of oral and nasalized vowels largely depend on the acoustic features by which the task is performed. In this thesis, sets of acoustic ...
