With the proliferation of wireless networks, there is a need for more compact, low-cost, power efficient transmitters that are capable of supporting the various communication standards, including Bluetooth, WLAN, GSM/EDGE, WCDMA and 4G of 3GPP cellular. This book describes a novel idea of RF digital-to-analog converters (RFDAC) and demonstrates how they can realize all-digital, fully-integrated RF transmitters that support all the current multi-mode and multi-band communication standards.

With this book the reader will:

Understand the challenges of realizing a universal CMOS RF transmitter
Recognize the design issues and the advantages and disadvantages related to analog and digital transmitter architectures
Master designing an RF transmitter from system level modeling techniques down to circuitdesigns and their related layout know-hows
Grasp digital polar and I/Q calibration techniques as well as the digital predistortion approaches
Learn how to generate appropriate digital I/Q baseband signals in order to apply them to the test chip and measure the RF-DAC performance.

Highlights the benefits and implementation challenges of software-defined transmitters using CMOS technology
Includes various types of analog and digital RF transmitter architectures for wireless applications
Presents an all-digital polar RFDAC transmitter architecture and describes in detail its implementation
Presents a new all-digital I/Q RFDAC transmitter architecture and its implementation
Provides comprehensive design techniques from system level to circuit level
Introduces several digital predistortion techniques which can be used in RF transmitters
Describes the entire flow of system modeling, circuit simulation, layout techniques and the measurement process
