BROADBAND NON-INVERTING AMPLIFIER WITH LOW NON-LINEAR NOISE AND HARMONIC DISTORTION Russian patent published in 2014 - IPC H03F3/45 

FIELD: radio engineering, communication.

SUBSTANCE: broadband non-inverting amplifier comprises a non-inverting output stage (1), the input of which is connected to the input of the device (2) and an input voltage source (3) through a matching resistor (4), a load circuit (5) connected to the output (6) of the device, connected to the output of the non-inverting output stage (1). Between the input (2) and output (6) of the device there are inverting buffer amplifier (7), the second (8) and the third (9) auxiliary resistors installed, connected in series. The common assembly of the resistors is connected to the input of correcting stage (11), whose current output (12) is connected to the input of non-inverting output stage (1).

EFFECT: lower level of nonlinear distortions and different types of noise in the load circuit of the broadband non-inverting amplifier with a non-inverting output stage.
