HIGH-SPEED OPERATIONAL AMPLIFIER WITH BRIDGE INPUT DIFFERENTIAL STAGE Russian patent published in 2023 - IPC H03F3/45 

FIELD: microelectronics.

SUBSTANCE: invention relates to the field of microelectronics and can be used in various analog and analog-to-digital interfaces for processing signals from sensors of physical parameters. The technical result is achieved by the fact that a first and a second additional transistors, a first and a second additional reference current sources, a first and a second additional corrective capacitors are introduced into the circuit of the first buffer amplifier, in addition, a third and a fourth additional transistors, a third and a fourth additional reference current sources, a third and a fourth additional corrective capacitors are introduced into the circuit of the second buffer amplifier.

EFFECT: increasing the limit values of the output voltage slew rate without deteriorating the energy parameters of the operational amplifier in the static mode, as well as without using microwave technological processes for manufacture of the amplifier, thus reducing parasitic capacitances.
