7.82 A source follower is required to connect a high-resistance source to a load whose resistance is nominally 2 k but can be as low as 1.5 k and as high as 5 k. What is the maximum output resistance that the source follower must have if the output voltage is to remain within ±10% of nominal value? If the MOSFET has k n = 2.5 mA/V2, at what current I D must it be biased? At what overdrive voltage is the MOSFET operating?
