Question 2 The following parameters have been defined for the MOSFET amplifier circuit shown in Figure 2.1: VDD = 20 V, R1 = 2.2 MΩ, R2 = 1.8 MΩ, RD = 1.5 kΩ. (a) Given that the MOSFET has the parameters K = 0.475 mA/V2 and a turn-on voltage, Vto = 2.1 V, calculate the value of source resistance, Rs, needed to set a DC bias drain current of ID = 4 mA. [6 marks] (b) With Rs set at the value calculated in part (a), determine the value of the drain voltage, VD, and confirm whether or not the MOSFET is operating in the saturation region.
