1. The circuit of Figure 1 contains an independent voltage source VDD = (5000+a) mV and two MOSFETs whose parameters are as follows: Vin (500+ẞ) mV, μnCox = (300+y) μV/A², (W/L) = 6 µm/1 μm, λ = 0 V-¹; Vtp = -(500+5) mV, μpCox = (100+) μV/A², (W/L) = 2 µm/1 μm, p = 0 V1. (i) Calculate the current /D1 and the voltage Vos1. (10 points) (ii) Use LTSpice to calculate ID1 and VDS1. (5 points) (iii) If the results from (ii) are different from those in (i), explain why.
