DIFFERENTIAL AMPLIFIER WITH INCREASED DEPLETION OF COPHASED SIGNAL Russian patent published in 2006 - IPC H03F3/45 

FIELD: radio engineering, communications engineering, possible use in various microelectronic devices for amplification and transformation of analog signals.

SUBSTANCE: differential amplifier contains input differential cascade on first and second input transistors, emitters of which are connected to output of first current mirror, first and second transistors of input current compensation channel, bases of which are connected to bases of first and second input transistors, while emitters are connected to outputs of static mode stabilization circuit. Collectors of first and second transistors of input current compensation channel are connected to input of first current mirror.

EFFECT: increased depletion coefficient of input cophased signal.
