Wideband Amplifiers
by Dennis L. Feucht

On rare occasion, a book is published that the analog designer wants to have within arm's reach near one's desk. This 640 page hardbound book which comes with a matching CD is one of them.

The authors live in Slovenia, but hardly far from the analog state-of-the-art. The two are from the Jozef Stefan Institute in Ljubljana. I remember passing Peter occasionally while walking around the Tektronix campus in Beaverton, OR when he worked there and Erik has long been in contact with some of the leading oscilloscope vertical amplifier designers from Tek. The book has that European penchant for being theoretically complete and in-depth, in this case on the subject-matter of how to design fast dc amplifiers. Much of what was once proprietary company information at Tek is now explained in detail in the book. Yet, 25 or more years later, these concepts are not widespread in the electronics industry. That fact was also a motivation for why I wrote my book, Analog Circuit Design (ACKTS), which put into book form three large engineering looseleaf notebooks from my T&M instrument design work. It is now being offered as a four-volume set on CD or via e-mail attachment. Wideband Amplifiers is a good complement to it because it presents in more complete form what ACKTS covers in some of the High-Performance Amplifiers volume.
