Use of Operational Amplifiers in Precision Current Regulators
Karl Eklund · Review of Scientific Instruments · 1959
The design and construction of precision current regulators is simplified by the use of commercially available operational amplifiers. Their method of use is described and an example is given of a regulator used with an electron spectrometer, where the regulation obtained was 0.01%. It is felt that the use of operational amplifiers offers a great convenience to the physics laboratory.
