Research of operational amplifiers with nonlinear drivers of correction capacity

Transients of operational amplifiers (OA) with a unipolar circuit of RC-correction in the large signal operation are considered. In order to increase the fast response, the differential stages with various kinds of nonlinearity are used as a driver of the correction capacity: the output current confinement, the dead band in the central section of the passage characteristic, the passage characteristics with the sections of different slopes, etc. The recommendations for raising the maximal slew rate of the operational amplifiers of the considered class by a factor of 5÷100 have been developed.
