77. Consider the CS stage shown in Fig. 7.99, where M2 operates as a resistor. Figure 7.99 (a) Determine W2 such that an input dc level of 0.8 V yields an output dc level of 1 V. What is the voltage gain under these conditions? (b) What is the change in the gain if the mobility of the NMOS device varies by ±10% ? Can you explain this result using the expressions derived in Chapter 6 for the transconductance? In the following problems, unless otherwise stated, assume μnCox = 200 μA/V2, μpCox = 100 μA/V2, λ = 0, and VTH = 0.4 V for NMOS devices and −0.4 V for PMOS devices.
