However, in certain circuits, op amps have imperfections which break the golden rules. The last two week’s exercises should have convinced you that op amps behave ideally in a wide range of useful circuits. How does the push-pull circuit in 8.11 work? What do you think is the origin of the name? Why does the capacitor in 8.3 mask 60Hz noise?ģ. Explain why it is necessary to divide by 1000 to obtain the input offset vol t age V os in 8. Perform any circuit calculations use MatLab or anything that can be done outside of lab RStudio (freeware).Īll parts spec sheets are located on the Physics 111 Library site.ġ.Answer the pre-lab questions utilizing the references and the write-up.This week’s lab explores some of these circuits, and investigates methods of curing some of the imperfections.īefore coming to class complete this list of tasks: However, some circuits expose op amp imperfections which violate the golden rules. In many circuits, op amps behave perfectly in the sense that the op amp golden rules are obeyed. NOTE: You can check out and keep the portable breadboards, VB-106 or VB-108, from the 111-Lab for yourself ( Only one each please) Reprints and other information can be found on the Physics 111 Library Site.
