DIFFERENTIAL INSTRUMENTATION AMPLIFIER WITH PARAPHASE OUTPUT Russian patent published in 2017 - IPC H03F3/45 

FIELD: physics.

SUBSTANCE: differential instrumentation amplifier with the paraphase output is proposed, that contains a non-inverting device input (1) and the in-phase non-inverting device output (2), an inverting device input (3) and the in-phase inverting device output (4), the first (5) front differential cascade, the second (8) input differential cascade, an output differential cascade (14). An additional differential cascade (20) is introduced in the circuit, the non-inverting input (21) of which is connected to the non-inverting (1) device input, the inverting input (22) of the additional differential cascade (20) is connected to the inverting (3) device input, the first (23) current output of the additional differential cascade (20) is connected to the first (12) current output of the second (8) input differential cascade, and the second (24) current output of the additional differential cascade (20) is connected to the second (16) current output of the second (8) input differential cascade.

EFFECT: increasing the coefficient value of the voltage transmission.
