hello frens,


buffer is nothing but two inverters combination..then what makes the difference can u plz help me...it s urgent

(Voltage) buffer properties: Very high input resistance and very low output resistance and unity gain.

If you speak about opamp realizations: Inverters have only medium range input resistances (kOhm range). Thus two inverters in series have bad buffer properties and 2 opamps are necessary (waste of money).
 
I think you use buffer (two inverters in series) can help improve the slew rate: it means rise/fall time is very small. It is very usefull if you place buffer at the output of comparator.

Hope this help!

In simple terms, Inverter takes an input signal and inverts it ( e.g 0 in 1 out, or 1 in 0 out).

Buffer on the other hand, does not invert the signal, it simply makes the signal a little stronger.

Hope this helps.
 
What you said is correct. The difference is in the functionality. Inverter gives inversion of input in outptut while buffer output is same as input.
