Preface
Receivers have been a basic block in telecommunication systems since the invention of the radio in the late 19th century, acquiring an essential role in what has been called the third Communication Revolution where information is transferred via controlled waves and electronic signals. Their main function is to recover the information from the transmitted wave and convert it to electronic signals that can be understood by the succeeding electronic processing signal systems. Since the Internet revolution, new receivers appeared to connect computers one to another or to the World Wide Web, such as wireless systems, have been gaining more and more popularity over the last few years. Thus, great investments in time, effort and money from both academia and industry have been made in the development of these receivers in order to achieve fully integrated solutions in form of ASICs meeting the demand for ever increasing high performance with low cost, low voltage supply, low power consumption and reduced surface area. The design of one of these receivers include different blocks such as filters, low noise amplifiers, gain controlled amplifiers, mixers and analog to digital converters. This book is precisely focused on the analysis and design of automatic gain control, AGC, circuits with wireless receivers as the main target application. In this context, the general function of the AGC circuitry is to automatically adjust the output signal of a variable gain amplifier to an optimal rated level, for different input signal
