Tradeoffs: Should I Use an Integrated Analog IC or Individual ICs?
Brad Albing  
12/31/2013   24 comments
Highly integrated analog ICs are perfect for some applications and can be real money-savers. But sometimes, it works out better to pursue your design in a non-integrated manner.
Can We Have Rad-Hard Integrated Analog?
Brad Albing  
12/30/2013   49 comments
Integrated analog is fairly easily done now, but rad-hard parts must play by different rules. Can we actually make rad-hard integrated analog?

What Do You Need for High-Rel & Rad-Hard Applications? Part 3
Paolo Scalisi  
12/24/2013   7 comments
Designing products for the ultra-harsh environment of outer space is not easy. All the parts need to withstand the extremes of temperature. Worse yet, they need to tolerate radiation from high energy particles and photons.
