AMPLIFIER WITH DISTORTION CORRECTION OF OUTPUT CASCADE Russian patent published in 2019 - IPC H03F3/181 

FIELD: physics.

SUBSTANCE: invention relates to the computer equipment. Amplifier without common feedback consists of pre-amplifier with differential inputs, inverting input of which has connections to output of this amplifier through resistor 10 and with common wire through resistor 9, and non-inverting input is connected to first output of resistor 8, second output of which is connected through input signal voltage source with common wire, and output stage in form of amplifier voltage repeater connected by voltage follower, which output through load is connected to common wire, and its non-inverting input is connected to preamplifier output, besides, resistor 15 connected between non-inverting input of pre-amplifier and its output is introduced, and resistor 16 connected between inverter input of pre-amplifier and output stage amplifier output, at that resistors resistances 10 and 16 are equal, and resistance ratio of resistor 15 to resistance of resistor 8, reduced by one, is equal to resistance ratio of resistor 10 to resistance of resistor 9.

EFFECT: technical result consists in improvement of output cascade characteristics.
