In the circuit shown in Figure 1, if the voltage VDS (=VGS) and the current ID are known for two different values of VDD, the parameters Vt and K can be computed from 2 I_D = K( V_GS - V_t)². Write out the expressions for Vt and K in terms of ID and VGS. Based on ID=0.1 mA for VDD=4 V and ID=0.2 mA for VDD=8 V, determine values of Vt and K.
