An undergraduate and industry reference text offering coverage of the field of operational amplifiers for first- and second-year modules and HND units. This edition is revised to cover all the developments in the area and to match degree module syllabuses in the UK and USA. The introductory sections have been expanded so that only a basic grounding in electronics is assumed. The layout has been redesigned to make it easier to use. New, updated and expanded topics include feedback op-amps, Bi-FET devices, CMOS devices, single supply operation, differential amplifier ICs and low voltage op-amps.
