A source follower is required to connect a high-resistance source o a load whose resistance is nominally 2 kΩ but can be as low as 1kΩ and as high as 3 kΩ. What is the maximum output resistance that the source follower must have if the output voltage is to remain within ±20% of nominal value? If the MOSFET has kn = 16 mA/V2, at what current ID must it be biased? At what overdrive voltage is the MOSFET operating?
