a source follower is required to connect a high resistance source to a load whose resistance is nominally 2k ohm but can be as low as 1k ohm and as high as 3k ohm. What is the maximum output resistance that the source follower must have if the output voltage is to remain within + or - 20% of nominal value? If the MOSFET has kn = 16 mA/V^2, at what current ID must it be biased? At what overdrive voltage is the MOSFET operating.
