Re: Re : Interleaving Spurs: Let's Look at the Math
Math is what calculators are for right? And of course while we get to tinker around with the engineering and designing and stuff, we need to make sure that everything goes somewhat successfully right from the get go! But I love your analogy here. I'm definitely looking forward to trying some things out on my own!

That is correct Sunita.  Now that we've explored the mismatches, I thought it appropriate to start quantifying the level of the spurs caused by these mismatches.

Re : Interleaving Spurs: Let's Look at the Math
There are several challenges to look out for while interleaving ADCs.  Spurs appear in the output band that outcomes from the inadequacies related with inter leaving ADCs.  The deficiencies are essentially misalliances between the 2 ADCs that are interleaved.  There are 4 elementary misalliances that outcome in spurs in the production of band.  These are gain mismatch, offset mismatch bandwidth mismatch and timing mismatch.

Iíd like to take a step back from the details and specifics related to radiation testing and focus a bit on some of the reasons that advanced testing and screening is performed on space qualified products.
Technically an SET could also be considered as an SEU for a high speed ADC since it is likely that an ion strike could cause an SEU that results in a transient event that we would call an SET.
Iíd like to take a little more time to look at SETs. There are a few more points that Iíd like to cover on the topic before we move on to SEUs.
Now letís move to our next SEE topic which is single event transients (SETs)
In this installment we will look at single event latch-up (SEL) in particular for high speed ADCs.
