Features: Operational amplifiers (OpAmps, abbreviated as OpAmps) are considered magical and versatile devices, playing a pivotal role in many electronic systems. By utilizing OpAmps, various functions such as signal amplification, conditioning, and filtering can be achieved, with widespread applications in fields like personal digital assistants, communications, automotive electronics, audio-visual products, instruments, and sensors. Professor Johan H. Huijsing, the author of this book, has long been engaged in research on OpAmp theory, design, and applications, having published hundreds of academic papers and dozens of patents, and has independently or collaboratively completed over ten academic books. He holds a high international reputation and influence in the field of analog circuits. This book enables circuit designers to gain a clearer and deeper understanding of OpAmp theory and design. Its core is to categorize all OpAmps into nine main topological structures and systematically introduce OpAmp circuit design. This classification method helps circuit designers quickly identify, understand, and select appropriate OpAmp structures. These nine types of amplifiers cover amplifier structures ranging from one to four or more stages. The book provides a comprehensive evaluation of many famous design forms and presents compensation techniques for all nine types of amplifiers in high-frequency conditions, particularly highlighting low-voltage, low-power structures with Rail-to-Rail input and output ranges. It also offers an in-depth discussion on the design of fully differential OpAmps and floating-point OpAmps. Additionally, by combining parameter measurement techniques, OpAmps are characterized in the form of macro models and error matrices.
