Electronic circuit design

Ultra-Wide band (UWB) systems are a new wireless technology capable of transmitting
data over a wide spectrum of frequency bands with very low power and high data rates.
This technology has the potential to replace almost every cable at home or in an office
with a wireless connection. In a UWB receiver, a radio frequency (RF) low noise
amplifier (LNA) is one of the most important components. This thesis discusses the entire
process involving the design ofUWB low noise amplifiers including a detailed stage by
stage analysis of a computer aided design (CAD) of a MOSFET UWB LNA. Simulation
tools and concepts from Level I equations are used in order to design a circuit with a
realistic MOS model such as the BSIM3 used in this work. The LNA shows improved
power consumption over the designs it is based on while still producing comparable
results.

Signal Integrity is a major bottleneck for DSM designs. Signal integrity refers to wide variety of problems, which leads to misconception. Signal integrity causes delay or noise at the high-level, but this boils down to resistance, capacitance and inductance (RLC) at circuit level. Several analysis and reduction techniques were proposed for reducing these effects on signal integrity. This work solves the misconception by encompassing different problems Chat effect signal integrity and can be good reference for a integrated circuit designer. The objective is to analyze these modeling methods, reduction techniques, tools and make recommendations that aids in developing a methodology for perfect design closure with an emphasis on signal integrity. These recommendations would form a basis for developing a methodology to analyze interference effects at higher levels of abstraction.
