In the following problems, unless otherwise stated, assume μnCox = 200 μA/V2, μpCox = 100 μA/V2, and VTH = 0.4 V for NMOS devices and −0.4 V for PMOS devices.41. If λ = 0, what value of W/L places M1 at the edge of saturation in Fig.6.53 ? 42. With the value of W/L obtained in Problem 41, what happens if VB changes to +0.8 V ? Figure 6.53
