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.

Staszewski, Robert Bogdan
Before becoming a university professor in 2009, Robert Bogdan Staszewski was a design engineer / industrial researcher for over 18 years, working in microelectronics and communication systems. He concentrated on large system-on-chip (SoC) designs for wireless applications and before that was involved in analog, RF, mixed-signal and digital designs. His approach is always to discover novel solutions that offer clear advantages over existing designs. His commitment to innovation and quality has resulted in him developing tens of full-custom mixed-signal complex IC chips. He is an IEEE Fellow for his contributions to the digital RF communications systems.
