Well over a billion people are currently using cellular telephones, and this number is expected to grow to over two billion in the next few years. It is remarkable that a device that was considered a high-technology "toy" just a few years ago is now an indispensable feature of modern life. One of the key reasons for this remarkable transformation is the integration of all the radio functions of a cellular telephone onto a single inexpensive piece of silicon. This achievement is a result of innovations in design and process technology that allowed formerly discrete and separate devices to be integrated onto a common substrate.

Now that this integration has been accomplished, the next challenge is to make these radio functions adaptive to their environment. This "adaptive" feature of wireless communications devices is just today becoming a reality, and Adaptive Low-Power Circuits for Wireless Communications represents one of the first comprehensive treatments of the subject.

Adaptive radio transceivers require a comprehensive theoretical framework in order to optimize their performance. Adaptive Low-Power Circuits for Wireless Communications provides this framework with a discussion of joint optimization of Noise Figure and Input Intercept Point in receiver systems. Original techniques to optimize voltage controlled oscillators and low-noise amplifiers to minimize their power consumption while maintaining adequate system performance are also provided. The experimental results presented at the end of the book confirm the utility of the proposed techniques.
