NON-INVERTING OUTPUT STAGE OF A GALLIUM OPERATIONAL AMPLIFIER Russian patent published in 2022 - IPC H03F3/45 

FIELD: operational amplifiers.

SUBSTANCE: invention can be used as an output stage of operational amplifiers. To achieve the effect, a non-inverting output stage of a gallium arsenide operational amplifier is proposed, which contains an input (1) and an output (2), an input (3) field effect transistor, an auxiliary (4) field effect transistor, the first (5) bus, the first (6) output bipolar transistor, second (7) output bipolar transistor, terminating resistor (8), second (9) bus. The drain of the input (3) field effect transistor is connected to the source of the auxiliary (4) field effect transistor and the base of the first (6) output bipolar transistor through a terminating resistor (8), and the source is connected to the output (2), the emitter of the first 6 output bipolar transistor is connected to the first (5) bus, and its collector is connected to the output (2) of the device, and the emitter of the second (7) output bipolar transistor is connected to the output (2) of the device, and its collector is connected to the second (9) bus.

EFFECT: ensuring a voltage transfer coefficient close to unity, a small static consumption current, as well as providing two-way currents in a relatively low-resistance load.
