Assume that the resistors have 1% tolerance and determine the Common

Mode Rejection Ratio (CMRR) of the setup and estimate its bandwidth. We

invite the reader to view the recorded lecture [18].

Frequency Response - Obtain the gain bandwidth product of the unity gain

amplier, the inverting amplier and the non-inverting amplier from the

frequency response.

DC Transfer Characteristics - Study the saturation limits for an OP-Amp.

Determine the second pole of an OP-Amp and develop the macromodel for the

given OP-Amp IC TL082. See Appendix B for an introduction to the topic of

analog macromodels.
