This book contains the extended and revised versions of the talks of all speakers presented at the sixth AACD Workshop held in Villa Olmo, April 2-4 1997 Como, Italy. The local chairman was Pietro Erratico and the organization was performed by Isabella De Quattro both of SGS Thomson Microelectronics Cornareda and Agrate Brianza Italy. The program consisted of six tutorials per day during three days. These tutorials were presented by experts in the field to give state of the art information. Program topics for the following workshop are selected by the audience at the end of the workshop. The program committee, consisting of 10han Huijsing of Delft University of Technology, Willy Sansen of Katholieke Universiteit Leuven and Rudy van de Plassche of Philips Research Labs and University of Technology Eindhoven elaborates the selected topics into a three day program and selects the experts in the field for presentation. Each AACD Workshop has given rise to the publication of a book by Kluwer entitled "Analog Circuit Design". This series of six books in a row provides a valuable overview of all analog circuit techniques concerning design, CAD, simulation and device modeling and can be seen as a reference to those involved in analog circuits.
