Abstract

The invention concerns devices to amplify electric signals and more particularly, differential amplifiers. The object of the invention is creation of a differential amplifier which is symmetric with regards to the power source (+U, -U) the balancing of which does not depend on the parameter difference of amplifying elements. The objects is achieved by execution of a differential amplifier under circuit of the series balance, that lets to obtain the symmetry of a differential amplifier with regards to the power source (+U, -U) and its balancing does not depend on the parameter difference of amplifying elements (1, 2).
