Design and Construction of High Slew Rate Amplifiers

Document Thumbnail

This thesis concerns: 1) The design of an audio power amplifier that features a large amount of negative feedback over a wide range, yet has a high slew rate and low Transient Intermodulation Distortion (TIM). 2) The technical difficulties involved in the design of amplifiers based on a conventional single-pole compensation design, and advantages of a two-pole compensation design. 3) The proposed new circuit configuration for high slew rate. 4) The results of measurements of how much electric current flows in each compensation circuit of experimentally built power amplifiers, compared with the results of computation based on inverse Laplace transform. 5) Finally, the construction of an amplifier with a high slew rate of about 1,000V/usec.
