Acknowledgments

This book is the result of years of teaching in the Electronic Systems and Electronics courses at the Master in Electronic Engineering at Politecnico di Milano. Many grateful thanks to all PhD students who contributed to let this book become real.

This book deepens and complements concepts, components, and circuital stages introduced in the book Electronics, which provided the basics to analog and digital electronic component and electronic circuits design. Aim of this Electronic Systems book is to provide further advanced topics, integrated circuits and circuital configurations to students and engineers working in the many fields of design and development of electronic products and systems.

This is the first release in English of the book. Many grammar errors are still to be corrected and the quality of the English text will be further improved, for sure. I wish to apologize for such an inconvenience. However I preferred to deploy a text book as soon as possible to help students in the Master in Electronic Engineering.

My best appreciations to some of my PhD students, namely Simone Bellisai, Andrea Bahgat Shehata and Bojan Markovich, for the reviews, the translations, the lunches together and the nice atmosphere in the labs. My best gratitude to Hazar Yuksel, for a comprehensive revision of most chapters and an in-depth improvement of its fluency. Eventually my devoted gratitude to enthusiastic and charming Federica Villa, whose support did, does and will keep me teaching while smiling and the other way round, too.

Operational Amplifiers

Everybody screamed when I kissed the teacher

and they must have thought they dreamed when I kissed the teacher

All my friends at school

they had never seen the teacher blush, he looked like a fool

Nearly petrified cos he was taken by surprise

When I kissed the teacher

Couldnt quite believe his eyes, when I kissed the teacher

My whole class went wild

As I held my breath, the world stood still, but then he just smiled
