Abstract :
Precise formulas for the step response and the settling time of op-amps are given. The formulas cover the slew as well as the quasilinear region of the op-amps. The amplifiers are modelled to have a nonlinear input stage and a single pole. The input transistors of the op-amp may be bipolar or MOS working in weak inversion.
