Using the data given in the example of Section 1.9, include the effects of substrate leakage in the calculation of the output resistance for the circuit of Problem 4.5. Let V_OUT= 2Vand 3V?

Data from 4.5

Calculate the output resistance of the circuit of Fig. 4.9, assuming that I_IN =100 µA and the devices have drawn dimensions of 100 µm/1 µm. Use the process parameters given in Table 2.4, and assume for all devices that X_d = 0. Also, ignore the body effect for simplicity. Compare your answer with a SPICE simulation and also use SPICE to plot the I_OUT-V_OUT characteristic for V_OUT from 0 to 3 V?
