The noise in operational amplifiers
Abstract
General characteristics of noise as a statistical parameter are considered, taking into account statistical relations, Johnson noise, and current noise. Significant noise parameter relations are examined along with aspects of operational amplifier evaluation. An investigation is conducted concerning the conditions in an operational amplifier with feedback, giving attention to amplifiers with parallel feedback and with series feedback. Basic circuits for noise measurements in operational amplifiers are discussed.
