A pseudo-NMOS Schmitt trigger is shown in Fig 5.2.To ease hand calculations, you may assume that the PMOS transistor remains in saturation over the entire range of operation.(W/L)1 = 1.8/1.2 and (W/L)2,3,4 = 18/1.2.
a.Compute VOH and VOL.
b. Compute the switching points VM+ (for the input making a low-to-high transition) and VM- (for the input making a high -to- low transition) .
out M2 in Figure5.2. Pseudo-NMOS Schmitt trigger
