packing density of nmos and pmos

hello friends,
lets talk about which is better either "nmos" or "pmos" or "CMOS",.. why and how .. in all the aspects power speed n advantages... this will be very useful to all...

hi

I think that the future of the electronics industry is going on the CMOS since it is the best from all aspects...density,power ,noise .

some of the points which i can think of :

1. NMOS can produce a strong 0, but only weak 1(vice versa for PMOS). CMOS can produce strong 1 and a strong 0,i.e. output swings from rail-to-rail.

2. Static power dissipation in NMOS was a problem, CMOS was preferred to NMOS because of this.

3. has much better carrier mobility compared with PMOS but not as high as NMOS(should be self-evident).

4. high noise margins and robustness compared to other technologies

correct me if i've gone wrong somewhere

an area where nmos scores over cmos is integration...

nmos has the highest packing density of all logic families... and obviously preferred ove pmos for mobility reasons as above...
