This book is a monograph, which summarizes the research results of the author in the field of the analysis, design and modelling of small-signal amplifiers and some of their general applications (up to 500MHz), employing various types of monolithic operational amplifiers. In particular, the material in the book covers the following topics and subtopics: - Basic definitions and classifications of the analogue circuits. Feedback amplifier analysis; - Behavioural modelling of monolithic operational amplifiers by using VHDL-AMS and Analogue Behavioural Modelling feature in the Cadence PSpice(r)...
