The BJT circuit design of the high-speed operational amplifier (op-amp) is considered, in which a significant increase in the maximum slew rate (SR) is provided by introducing differentiating circuits for correcting the transient in the input stage (IS) of the op-amp. As a result of computer simulation, the limiting values of the SR (up to 2900 V/µs) are established, which are implemented in the op-amp with the ideal current mirrors and an ideal buffer amplifier
