It is consider the nonlinear operating mode of an operational amplifier (op-amp) with the transfer function of the first order. The correction capacitor driver has exponential feed-through characteristics. Such circuitry solution of the op-amp provides high currents of recharge of the correction capacitor and low power consumption in the static mode. The analytic estimates of the transient’s time and the maximal slew rate of the output voltage of op-amp.
