Advice from analog gurus on how to approach analog/mixed signal IC design interviews?

Hi everyone,

I am looking for tips on how to approach analog mixed signal design interviews. To note, I am based in the Silicon Valley.

A little about me, I worked in the AMS industry for 1 yr; during which, I successfully designed and taped out a type 2 integer-N Charge pump PLL, a Synchronous SAR ADC, and a Bandgap (all of those had lots of senior guidance). But after a year, I had to leave for family reasons. I also have an MS from a top AMS university.

Fast forward to now, I've interviewed at a few companies and have performed unsuccessfully. Would any analog gurus be willing to shed some light on how to pass the intense white boarding sessions? Does anyone have a set of fave questions they'd be willing to share with me? (PLL, ADC, OPAMPs/OTAs, etc???)

I love analog design and have dedicated the last 3 yrs of my life to studying it. So any advice is appreciated.

Thanks and happy holidays! Cacteo.
