| Question of the Day: |
|
What is the input and output resistance of a circuit? How can you use the Circuit System Design Cards to find this? What is a voltage follower? Why is it also called a buffer? When and why do you need to use a buffer? How does the output voltage for a Circuit System Design Card relate to the Thevenin equivalent output voltage? |

Introduction: When combining op-amp (or other) circuits in series, the ideal 'standard' models we have developed in previous lectures work only if the output resistance of the first circuit is small compared with the input resistance of the circuit it is connected to. If it isn't, then we can use a buffer to make it that way.
