Design Of A CMOS VCO And Frequency Divider For 5 GHz Applications
(Electrical Engineering, 2007-08-23)
This thesis presents the design of a new CMOS Voltage Controlled Oscillator and a frequency divider, both of which form important blocks in the design of a PLL synthesizer. These components are important because they operate ...
A Functional Link Network Using Ordered Basis Functions
(Electrical Engineering, 2007-09-17)
A new function approximation and classification network based on Functional Link Network (FLN) with orthonormal Polynomial Basis Functions (PBF) is presented. By using an iterative Gram-Schmidt procedure, the PBF's are ...
Sequences Of Near-optimal Feedforward Neural Networks
(Electrical Engineering, 2007-09-17)
In order to facilitate complexity optimization in feedforward networks, several integrated growing and pruning algorithms are developed. First, a growing scheme is reviewed which iteratively adds new hidden units to ...
A Piecewise Linear Classifier
(Electrical Engineering, 2007-08-23)
A piecewise linear network is discussed which classifies N-dimensional input vectors. The network uses a distance measure to assign incoming input vectors to an appropriate cluster. Each cluster has a linear classifier for ...
Fabrication Of A Silicon Single Electron Transistor
(Electrical Engineering, 2007-09-17)
Single electronics has bright prospects because of its high scalability. The single electron transistor (SET) which utilizes these principles could replace the current workhorse of the industry, the MOSFET.
The SET is ...
