  1. Example on output voltage clipping

  2. Closed loop gain of noninverting op amp (a) (b) Solving, we have V0, max = 2.44 V

  3. (c) Clipping occurs at output voltage of 12 V or input voltage of 3 V

  4. Slew-Rate Limitation As an example, assume we have a waveform, and we have to determine the output of the op-amp having a slew rate of 0.5 V/s

  5. Full-Power Bandwidth The o/p voltage is: Taking derivative, we have: The maximum rate of the o/p voltage change is then equal to the slew rate: Thus the full-power bandwidth is: Thus, and undistorted full-amplitude sinusoidal voltage is possible only for frequencies less than fFP

  6. DC Imperfections: Input bias current: Input offset current:

  7. Model of op-amp with imperfections Unequal current flowing in the terminals and unequal voltages applied , as seen by an external source applied. Ideal op Amp
