Hi there, I am looking for some help on a circuits question. It goes as follows,A source follower is required to connect to a high resistance source to a load whose resistance is nominally 2kOhm, but can vary between 1.5K and 5KOhm. What is the maximum output resistance that the source follower must have if the output voltage is to remain with +/- 10% of the nominal value.
