The Design of CMOS Radio-Frequency Integrated Circuits: Edition 2

Cambridge University Press
Free sample

This book, first published in 2004, is an expanded and thoroughly revised edition of Tom Lee's acclaimed guide to the design of gigahertz RF integrated circuits. A new chapter on the principles of wireless systems provides a bridge between system and circuit issues. The chapters on low-noise amplifiers, oscillators and phase noise have been significantly expanded. The chapter on architectures now contains several examples of complete chip designs, including a GPS receiver and a wireless LAN transceiver, that bring together the theoretical and practical elements involved in producing a prototype chip. Every section has been revised and updated with findings in the field and the book is packed with physical insights and design tips, and includes a historical overview that sets the whole field in context. With hundreds of circuit diagrams and homework problems this is an ideal textbook for students taking courses on RF design and a valuable reference for practising engineers.

The best strategies in healthcare begin with empathy

Revolutionary advances in medical knowledge have caused doctors to become so focused on their narrow fields of expertise that they often overlook the simplest fact of all: their patients are suffering. This suffering goes beyond physical pain. It includes the fear, uncertainty, anxiety, confusion, mistrust, and waiting that so often characterize modern healthcare.

One of healthcare’s most acclaimed thought leaders, Dr. Thomas H. Lee shows that world-class medical treatment and compassionate care are not mutually exclusive. In An Epidemic of Empathy in Healthcare, he argues that we must have it both ways—that combining advanced science with empathic care is the only way to build the health systems our society needs and deserves. Organizing providers so that care is compassionate and coordinated is not only the right thing to do for patients, it also forms the core of strategy in healthcare’s competitive new marketplace. It provides business advantages to organizations that strive to reduce human suffering effectively, reliably, and efficiently.

Lee explains how to develop a culture that treats the patient, not the malady, and he provides step-by-step guidance for unleashing an “epidemic of empathy” by:

Developing a shared understanding of the overarching goal—meeting patients’ needs and reducing their suffering Making empathic care a social norm rather than the focus of economic incentives Pinpointing and addressing the most significant causes of patient suffering Collecting and using data to drive improvement

Healthcare is entering a new era driven by competition on value—meeting patients’ needs as efficiently as possible. Leaders must make the choice either to move forward and build a new culture designed for twenty-first-century medicine or to maintain old models and practices and be left behind.

Lee argues that empathic care resonates with the noblest values of all clinicians. If healthcare organizations can help caregivers live up to these values and focus on alleviating their patients’ suffering, they hold the key to improving value-based care and driving business success.

Join the compassionate care movement and unleash an epidemic of empathy!

Thomas H. Lee, MD, is Chief Medical Officer of Press Ganey, with more than three decades of experience in healthcare performance improvement as a practicing physician, leader in provider organizations, researcher, and health policy expert. He is a Professor (Part-time) of Medicine at Harvard Medical School and Professor of Health Policy and Management at the Harvard School of Public Health.

It is hardly a profound observation to note that we remain in the midst of a wireless revolution. In 1998 alone, over 150 million cell phones were sold worldwide, representing an astonishing 50% increase over the previous year. Maintaining such a remarkable growth rate requires constant innovation to decrease cost while increasing performance and functionality. Traditionally, wireless products have depended on a mixture of semicond- tor technologies, spanning GaAs, bipolar and BiCMOS, just to name a few. A question that has been hotly debated is whether CMOS could ever be suitable for RF applications. However, given the acknowledged inferiority of CMOS transistors relative to those in other candidate technologies, it has been argued by many that “CMOS RF” is an oxymoron, an endeavor best left cloistered in the ivory towers of academia. In rebuttal, there are several compelling reasons to consider CMOS for wi- less applications. Aside from the exponential device and density improvements delivered regularly by Moore’s law, only CMOS offers a technology path for integrating RF and digital elements, potentially leading to exceptionally c- pact and low-cost devices. To enable this achievement, several thorny issues need to be resolved. Among these are the problem of poor passive com- nents, broadband noise in MOSFETs, and phase noise in oscillators made with CMOS. Beyond the component level, there is also the important question of whether there are different architectural choices that one would make if CMOS were used, given the different constraints.
One of the most daunting challenges facing the new U.S. administration is health care reform. The size of the system, the number of stakeholders, and ever-rising costs make the problem seem almost intractable. But in Chaos and Organization in Health Care, two leading physicians offer an optimistic prognosis. In their frontline work as providers, Thomas Lee and James Mongan see the inefficiency, the missed opportunities, and the occasional harm that can result from the current system. The root cause of these problems, they argue, is chaos in the delivery of care. If the problem is chaos, the solution is organization, and in this timely and outspoken book, they offer a plan.

In many ways, this chaos is caused by something good: the dramatic progress in medical science--the explosion of medical knowledge and the exponential increase in treatment options. Imposed on a fragmented system of small practices and individual patients with multiple providers, progress results in chaos. Lee and Mongan argue that attacking this chaos is even more important than whether health care is managed by government or controlled by market forces. Some providers are already tightly organized, adapting management principles from business and offering care that is by many measures safer, better, and less costly.

Lee and Mongan propose multiple strategies that can be adopted nationwide, including electronic medical records and information systems for sharing knowledge; team-based care, with doctors and other providers working together; and disease management programs to coordinate care for the sickest patients.
