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.
