The circuit shown in Figure 7 is supposed to work as an inverter where it has the following values for its parameters: VDD = 1.8V, lambda_1 = lambda_2 = 0, unCox = 100 uA/V2, upCox = 50 uA/V2, VTH,N=0.4V, VTH,P= -0.5V. (W/L)2 = 3/0.18 1. Assuming that vout,min = 0.1 V when vin = VDD, determine the mode of the transistors M1 and M2. 2. Using the previous results, determine the value of (W/L)1 that will guarantee that vout, min = 0.1 V, when vin = VDD.
