SUMMARY
The discussion focuses on the voltage swing in NMOS transistors as described in "Digital Integrated Circuits" by Jan M. Rabaey. Key points include the understanding that the voltage at node X charges to Vdd - Vtn1 due to the behavior of source followers M1 and M2, where M1 turns off when X exceeds Vdd - Vth. Additionally, the voltage drop across M2 can be negligible, leading to the conclusion that the swing is accurately represented as Vdd - Vtn1 rather than Vdd - Vtn1 - Vtn2, as the overdrive voltage does not cascade in this configuration.
