Frequency Compensation Techniques for Low-Power Operational Amplifiers

Intended for professional designers of integrated amplifiers, this book emphasizes low-voltage and low-power solutions. The book aims to bridge the gap between the professional designer's needs and available techniques for frequency compensation. It does so by explaining existing techniques and introducing several techniques including Hybrid Nested Miller compensation, Multipath Miller Zero cancellation and Multipath Conditionally Stable compensation. All compensation techniques are treated in a stage-number-based order, progressing from a single transistor to circuits with six stages and more. Apart from discussing the mathematical basis of the compensation methods, the book provides the reader with the factual information that is required for practising the design of integrated feedback amplifiers and worked out examples. What is more, many bipolar and CMOS operational amplifier realizations, along with their measurement results, prove the effectiveness of the compensation techniques in real-life circuits. The text focuses on low-voltage, low-power integrated amplifiers. The book should be useful for practicing analog design engineers and researchers in the field.It is also suitable as a text for an advanced course on the subject.
