Design of High Voltage xDSL Line Drivers in Standard CMOS [Hardcover]

This book fits in the quest for highly efficient fully integrated xDSL modems for central office applications. It presents a summary of research at one of Europes most famous analog design research groups over a five year period. The book focuses on the line driver, the most demanding building block of the xDSL modem for lowering power.

The book covers the total design flow of monolithic CMOS high voltage circuits. It is essential reading for analog design engineers.

Design of high voltage xDSL line drivers in standard CMOS fits in the quest for highly efficient fully integrated xDSL modems for central office applications. The book focusses on the line driver, the most demanding building block of the xDSL modem for lowering power. To reduce the cost, the cheapest technology is selected: standard CMOS, without any extra process options to increase the nominal supply voltage. The emphasis lies on the analysis, design and implementation of high voltage highly efficient line drivers in mainstream CMOS.

Design of high voltage xDSL line drivers in standard CMOS covers the total design flow of monolithic CMOS high voltage circuits. The book is essential reading for analog design engineers and researchers in the field and is also suitable as a text book for an advanced course on the subject.
