Adaptive Low-Power Circuits for Wireless Communications (Hardcover)
內容描述
Description
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.
