This book focuses on high performance radio frequency integrated
circuits (RF IC) design in CMOS. 1. Development of radio frequency
ICs Wireless communications has been advancing rapidly in the past
two decades. Many high performance systems have been developed,
such as cellular systems (AMPS, GSM, TDMA, CDMA, W-CDMA, etc. ),
GPS system (global po- tioning system) and WLAN (wireless local
area network) systems. The rapid growth of VLSI technology in both
digital circuits and analog circuits provides benefits for wireless
communication systems. Twenty years ago not many p- ple could
imagine millions of transistors in a single chip or a complete
radio for size of a penny. Now not only complete radios have been
put in a single chip, but also more and more functions have been
realized by a single chip and at a much lower price. A radio
transmits and receives electro-magnetic signals through the air.
The signals are usually transmitted on high frequency carriers. For
example, a t- ical voice signal requires only 30 Kilohertz
bandwidth. When it is transmitted by a FM radio station, it is
often carried by a frequency in the range of tens of megahertz to
hundreds of megahertz. Usually a radio is categorized by its
carrier frequency, such as 900 MHz radio or 5 GHz radio. In
general, the higher the carrier frequency, the better the
directivity, but the more difficult the radio design.
