This book investigates the design and implementation of low-voltage CMOS operational amplifiers, focusing on both single and two-stage architectures. It details the development of CMOS constant-gm input stages, highlighting their performance across rail-to-rail input common mode ranges. The text compares early circuits from Dutch universities with new designs from Ohio State University, covering their design, fabrication via MOSIS Tiny Chips, and characterization. While foundational knowledge of analog integrated circuit design is beneficial, the book's detailed explanations make it accessible to those with less experience.

This work is presented as an invaluable reference for advanced courses on low-voltage CMOS operational amplifiers and can be read by those with limited prior experience in analog circuit design due to its detailed explanations. The book covers the design, fabrication, and characterization of new circuits, building upon earlier developments in the field. Its focus on practical implementation and performance analysis makes it a significant contribution to the literature on analog integrated circuit design.
