If we connect nmos with vdd and pmos with ground then what is o/p of cmos inverter ckt?
also clearify that for what voltage ckt remains 1 and for what it becomes 0 if we consider with respect to input?
It becomes a class-B output stage with unity gain and a dead zone around 0V of several volts. Exactly, VTN+abs(VTP) ...
@Nebi Caka sir i think it doesn't act as exact buffer......it doesn't provide same voltage as in i/p.....so one can say it act as bad buffer,,,,as some voltage get lost i we see from characteristics.
Ritika, it becomes a class b output stage, with an inner dead zone. It is a structure well known in CMOS design but usually discarded due to the wide dead zone and to the fact that the bulk effect makes the gain fall down to 0.8 or 0.9.
@Francisco sir plzz elaborate ur explanation or provide source from where u get it.
Chapter 5 of the well known book by Gray and Meyer, devoted to output stages.
@Nebi Caka Sir as u told some voltage drop is there after swaping it doent act as proper buffer......i have a doubt that if we didnt swap it act as an inverter but in this case we get o/p as 5 or 0V....why there is not any voltage drop like in buffer...?
