This book tackles challenges for the design of analog integrated circuits that operate from ultra-low power supply voltages (down to 0.5V). Coverage demonstrates the signal processing circuit and circuit biasing approaches through the design of operational transconductance amplifiers (OTAs). These amplifiers are then used to build analog system functions including continuous time filter and a sample and hold amplifier.

This book is a compilation of chapters on various aspects of Ultra Wideband. The book includes chapters on Ultra Wideband transceiver implementations, pulse-based systems and one on the implementation for the WiMedia/MBOFDM approach. Another chapter discusses the implementation of the physical layer baseband, including the ADC and post-ADC processing required in the UWB system. Future advances such as multiantenna UWB solutions are also discussed.
