DIFFERENTIAL BRIDGE AMPLIFIER Russian patent published in 2006 - IPC H03F3/45 

FIELD: radio engineering.

SUBSTANCE: proposed amplifier (Fig. 3) that functions to amplify broadband and pulse signals in structure of various interfaces has input transistors 1 - 4 whose emitters are coupled with bases of respective output transistors 15 - 18, emitters of the latter being connected to those of respective input transistors 1 - 4 through additional resistors 24 - 26; inserted between emitters of output transistors 15 - 18 is resistor-diode matching sub-circuit 19.

EFFECT: enhanced speed due to reduced impact of collector junction capacitances on transient variables of nonlinear recharge processes.
