Think Femto capacitors too small to measure? Think again!

"Direct mismatch measurement of small capacitors is feasible and can be used for capacitors of different types" says PhD student Hesham Omran. The mismatch of a 2fF PIP capacitor was directly measured using simple test structure that can be automated and ported.   Read all about it at our newest paperDirect Mismatch Characterization of femto-Farad Capacitors, IEEE transactions on circuits and systems II, 2015.  

Congratulations hesham!
