8.80 A source follower for which and Vt = 0.5 V is required to provide a dc level shift (between input and output) of 0.8 V. What must the bias current be? Find gm, gmb, ro, Avo, and Ro. Assume that the bias current source has an output resistance equal to ro. Also find the voltage gain when a load resistance of 3 kΩ is connected to the output. 360 µA; 2.4 mA/V; 0.48 mA/V; 15 kΩ; 0.8 V/V; 0.33 kΩ; 0.72 V/V
