High-Speed Operational Amplifier with Differentiating Transient Correction Circuits

A scheme of a high-speed operational amplifier (Op-Amp) using differentiating correcting capacitors implemented on silicon pnp-and npn-BJTs of basic matrix crystals of OJSC “Integral” (Minsk, Belarus) is proposed. Computer modelling of the Op-Amp in the LTspice showed that the open-loop gain of the Op-Amp is close to 100 dB, and the limited output voltage slew rate (SR) increases due to the introduction of differentiating capacitors from 47 V/$\mu$s to 2000-4000V/$\mu$s. Recommended applications of the Op-Amp are ADCs drivers and analogue front-ends of physical values sensing elements in medicine, physics of high-energy and space apparatus.
