手头也有本E文的,关于音频功放的,Bob Cordell,《Designing Audio Power Amplifiers》About the Author
Bob Cordell is an electrical engineer who has been deeply involved in audio since his adventures with vacuum tube designs in his teen years. He is an equal-opportunity designer to this day, having built amplifiers with vacuum tubes, bipolar transistors, and MOSFETs. Bob is also a prolific designer of audio test equipment, including a high-performance THD analyzer and many purpose-built pieces of audio gear.
He has published numerous articles and papers on power amplifier design and distortion measurement in the popular press and in the Journal of the Audio Engineering Society. In 1983 he published a power amplifier design combining vertical power MOSFETs with error correction, achieving unprecedented distortion levels of less than 0.001% at 20 kHz.
Bob is also an avid DIY loudspeaker builder, and has combined this endeavor with his electronic interests in the design of powered audiophile loudspeaker systems. He and his colleagues have presented audiophile listening and measurement workshops at the Rocky Mountain Audio Fest and the Home Entertainment Show.
As an electrical engineer, Bob has worked at Bell Laboratories and other telecommunications companies, where his work has included design of integrated circuits and fiber optic communications systems. He maintains an audiophile website at www .cordellaudio.com, where diverse material on audio electronics, loudspeakers, and instrumentation can be found.
