3) A source-follower configuration, shown below, is employed as the output stage (last stage) of a cascade amplifier. It is required to provide an output resistance Ro = 150 2. You must include the channel length modulation effect, and it is known that i = 10mV!. V po ca R = = a) Draw the small-signal model of the circuit. If the MOSFET has 8m = 6.65 mA/V, find the required values of r, and the DC current source I. b) If the load resistance is R = 10052, what would be the obtained overall gain G? What would it be if the load is 10k ? (Assume the Rig from the previous stage is zero)
