Some Aspects of Discussion about Differential Amplifiers
Ling Jiang · Modern Electronics Technique · 2006
Differential amplifiers are widely used in electronic circuits.They are also one of the important subjects in simulate electronic technology.This paper describes that differential amplifiers overcome zero offset in direct coupling amplifier and amplify the difference voltage between the two input terminals in differential amplifiers.Meanwhile,it describes how to decrease the offset voltage under unsymmetrical conditions and the magnitude range of the common mode voltage.These will be helpful to circuit design and teaching.
