There are situations in which QN and QP of the CMOS inverter are deliberately mismatched
Chapter 14, Problem 14.35(choose chapter or problem)
There are situations in which QN and QP of the CMOS inverter are deliberately mismatched to realize a certain desired value for VM . Show that the value required of the parameter r of Eq. (14.40) is given by r = VM Vtn VDD Vtp VM For a 0.13-m process characterized by Vtn = Vtp = 0.4V, VDD = 1.3V, and n = 4p, find the ratio Wp/Wn required to obtain VM = 0.6VDD.
