Short leads, as close to the chip as possible

This appnote for A/D design http://www.linear.com/pc/downlo...1037,D4160 describes the effect of two inches of trace to the decoupling capacitor on an A/D. For those with an adversity to reading, it DOES have pictures. I know this thread is not about a/d, bit the pictures is the only illustration I know of the effects of 'decoupling' with traces not as short as possible.

you are an design engineer, you must know what is the power supply decoupling
I was about to writ something about misapplied titles, then I double checked and Abhishek, you are wrong, the title is "Software Developer". So, Priyanka, put those capacitors on, just take our word for it. If you were a "Hardware Developer", you would know that a wire from a to b is not an 'absolute'; connection.

                     i have seen your profile            01/01/70 00:00      
                        It seems to have changed            01/01/70 00:00

                        have a look            01/01/70 00:00      
                           Erik by god it is recently changed!            01/01/70 00:00      
   I think Neil is asking            01/01/70 00:00      
   Isn't this a 'C' problem rather than a RAM problem            01/01/70 00:00      
      Really?            01/01/70 00:00      
         code tested at simulator            01/01/70 00:00      
            So it's a hardware fault            01/01/70 00:00      
               Hardware tested            01/01/70 00:00      
                  answer to "why":            01/01/70 00:00      
                     but dont forget to put pull ups its port 0!            01/01/70 00:00      
                        for the test - yes, sure, sorry, I forgot            01/01/70 00:00      
                  "Hardware tested" and who gives a hoot            01/01/70 00:00      
                  Tested?!            01/01/70 00:00      
            it's the HW then            01/01/70 00:00      
         Yes, it looks like that.            01/01/70 00:00      
            Oh no it doesn't!            01/01/70 00:00      
               first of all, let me be clear ...            01/01/70 00:00      
                  not just stuck-at            01/01/70 00:00      
                     Good point!            01/01/70 00:00      
                        Let's give him credit ...            01/01/70 00:00      
                           yes it would, look here            01/01/70 00:00
