- Voltage swing for nmos is Vdd - Vth? How?
Ref: Digital Integrated Circuits by Jan M. Rabaey
I have trouble understanding two things:
1) Why will x charge to Vdd - Vtn1 and why not Vdd?
2) If x in left charges to Vdd - Vtn1, then in right also it would charge to Vdd - Vtn1... so Vy would charge to Vdd - Vtn1 - Vtn2... so why have they written the swing as vdd - Vtn1 and why not Vdd - Vtn1 - Vtn2?
