1. Why should readers want to read your book, Millimeter-Wave Digitally Intensive Frequency Generation in CMOS?

The design of RF frequency synthesizer remains one of the most challenging tasks at mm-wave frequencies because the synthesizer must meet the stringent requirements of low-cost, low-power, and low-voltage monolithic implementation in CMOS while also meeting the phase noise and switching transient specifications. In the past ten years, digitally-assisted and digitally-intensive phase-locked loop (PLL) architectures and techniques have been proposed and applied to the single GHz applications due to their advantages of improved RF performance and reduced silicon area and power consumption. This motivates the research on employing the digitally-intensive techniques for mm-wave frequency generation, which are more than 10 times higher than a single-GHz application.

If readers are interested in digitally-intensive PLL techniques, and especially in how to apply these techniques to mm-wave frequency synthesizers, this book will be very helpful as it describes the time-domain architectures and techniques that can be applied to mm-wave frequency synthesis to improve the performance while reducing the implementation cost.

This book is intended for graduate students, researchers, and practitioners in industry who study/work in electrical engineering, and are interested in mm-wave frequency generation for communication and radar applications, IC implementation, and time-domain circuit and system techniques. The practitioners working as RFIC design engineers will also be interested in and benefit from this book.

2. What subject areas and industries does this book directly relate to?

This book directly relates to the wireless industry, mm-wave radar industry (e.g., 77GHz automotive radar), and mm-wave communication industry (e.g., 60GHz high data rate communication, WiGig, and mm-wave back haul communication).

Major subject areas include CMOS integrated circuit design, radio frequency (RF) frequency synthesis, mm-wave frequency generation, mm-wave circuits design (e.g., oscillator, divider, multiplier), frequency synthesizer architecture, time-domain calibration techniques, design-for-test techniques.

3. What are the biggest pain points in the industry?

The biggest pain points in the mm-wave radar/communication industry are to obtain high system performance (e.g., high output power, high linearity, and high signal-to-noise ratio) with low power consumption and low implementation cost. Silicon Germanium and  III/V semiconductor technologies are conventionally used for mm-wave applications due to their high performance. However, their implementation cost are high, integration level are low, and are not compatible with the low cost CMOS technologies. In recent years, CMOS implementation of mm-wave system has become a major research and development field as it is potential for lower cost in mass production. To meet the stringent performance requirement of the mm-wave applications, digitally assisted and digitally intensive architecture and circuit design techniques are crucial.

4. What problems/challenges does this book address and what problem does it solve for your readers?

This book highlights the challenges of frequency synthesis at mm-wave band using CMOS technology. It compares the various approaches for mm-wave frequency generation (pros and cons) and introduces the digitally intensive synthesizer approach and its advantages. Detailed design techniques from system level to circuit level are provided in the book using a 60-GHz FMCW radar transmitter as a design example. The book also addresses system modeling, design-for-test, and layout issues related to mm-wave frequency synthesis.

The readers will learn the major mm-wave wireless applications and their requirement on frequency synthesis; the challenges and the opportunities of mm-wave frequency generation using CMOS technology; the pros and cons of both analog/digital intensive approaches. The readers will also learn the system level modeling techniques and mm-wave circuit design and layout tricks; learn how to partition a mixed-signal system into analog and digital portions and address the integration as well as isolation between them; learn the advanced time-domain circuit techniques for mm-wave oscillator; learn the advanced calibration techniques for achieving high spectral purity and wideband frequency modulation.

In summary, this book provides a comprehensive explanation on digitally intensive mm-wave frequency synthesis architecture, circuit implementation, system modeling, calibration techniques and testing techniques and procedures. The digitally intensive design methodology introduced in this book is very promising to help to solve the pain points in the mm-wave industry.

5. What topics and subjects does this book uniquely address and what value does it add to the industry?

In the book market now, these are no other books on the topic of digitally intensive frequency synthesis for mm-wave applications. Most of the relevant books are on phase-locked loop (PLL), which provides basic knowledge of PLL system and circuit design. And the design examples provided in these books are for frequency generation below 10 GHz. This book addresses the specific problems and difficulties of frequency generation at mm-wave frequencies. It is the first time the digitally intensive PLL architecture was applied to mm-wave frequency generation and the measurement results of the 60GHz prototype are very promising. This book uniquely compares the various frequency generation approaches for mm-wave frequencies and explains how to design a mm-wave digitally intensive PLL step by step. The authors believe that using digitally intensive architecture for mm-wave frequency generation is the trend for future mm-wave IC industry and the techniques discussed in this book will be very helpful for graduate student working on related topics and the engineers too.
