This book teaches basic and advanced concepts, new methodologies
and recent developments in VLSI technology with a focus on low
power design. It provides insight on how to use Tanner Spice,
Cadence tools, Xilinx tools, VHDL programming and Synopsis to
design simple and complex circuits using latest state-of-the art
technologies. Emphasis is placed on fundamental transistor
circuit-level design concepts.
The shrinking of device dimension leads to reduction of gate oxide
thickness. As a result of this the undesirable hot electron effect
and the gate tunneling current is increased. In order to overcome
this drawback high-k materials are used instead of silicon dioxide
as the insulating material underneath the gate. High-k dielectrics
are used in semiconductor manufacturing processes where they are
usually used to replace a silicon dioxide gate dielectric.Among
various high-k materials, Hafnium oxide (HfO2), Tantalum pent oxide
(Ta2O5) these materials appear to be the candidates for replacing
silicon oxide. These high-k dielectrics exhibit a trend of
decreasing barrier height with increasing dielectric constant.The
high-k materials with far higher permittivity create same gate
capacitance for thicker dielectric. In this book the main focus has
been on the modeling and the influence of depletion layers around
the source and the drain regions on the sub threshold surface
potential of a short-channel DMG MOS transistor with a
uniformly-doped channel.
A major issue of concern in the study of digital communication is
to provide a form of secure and interference free communication
system in a hostile environment. This requirement is catered by a
class of signaling techniques known as SPREAD SPECTRUM MODULATION.
In this technique the transmitted signal spectrum is spread over a
frequency range much greater than the message bandwidth . The
spectrum is accomplished before the transmission through the use of
code that is independent of data sequence. The same code is used in
the receiver (operating synchronously with the transmitter) to
de-spread the received signal so that the original message is
recovered.
