Sjoland H. Highly Linear Integrated Wideband Amplifiers...1999 torrent

Textbook in PDF format

This book deals with techniques for designing integrated wideband amplifiers with high linearity. It is intended for professional designers of integrated amplifiers and graduate students in this field. Amplifiers with operating frequencies from Audio to RF are covered. This book is based on my Ph.D. thesis, which was published in November 1997. The aim of the project, supervised by professor Sven Mattisson, was to design integrated wideband amplifiers with high linearity for different applications. In the book an enhanced feedback configuration called feedback boosting is described. It is capable of very low distortion. Theoretically a complete distortion cancellation can be achieved. Also described is a statistical method for relating the intermodulation distortion ofa wideband signal to the total harmonic distortion (THO) of a single tone. The motivation for this is that the THO, as opposed to the intermodulation distortion, is easy to measure and use as a design parameter. This method can handle both static and dynamic nonlinearities. High-performance amplifier designs are also presented, complete with measurement results and chip photos. The different designs cover operating frequencies from audio to RF. Two fully integrated CMOS class AB power amplifiers are described. They are capable of directly driving an 80 loudspeaker. One of the amplifiers can also operate on a supply voltage as low as 1.SY. Two wideband amplifiers are also presented, one in CMOS and one bipolar. They have high linearity from DC to 20MHz. Finally, a fully integrated CMOS RF power amplifier is described. It is built without using inductors, to investigate what performance then can be achieved
