  This flow was used in the process analysis of wireless product Zelda to find process dependencies of all specifications of the IC.
  The flow was integrated in a CAD product in NXP for all designer.

  devices that contribute on mismatch deviation during simulation.
  The software analyses the correlation between mismatch parameters and measurement from Monte-Carlo results. This flow has been implemented in Spectre and Cadence after a collaboration with Cadence R&D.

  and then the PLL pass into integer mode in normal mode when lock is done.
  The implementation is quite simple and does need only few digital gates.

  As a project leader of the new generation of the STV216X, I start development of product STV2162 (30mm² in HF3CMOS).
  I introduce new architecture with several digital implementations and new concepts in the IC.
  
  I did start the pre-study of next generation of scanning ICs for all type of CRT TV (Home, PC, VGA, Proscan,...) and for all type of frequencies.
  Because of high risk of CRT destruction due to fast change of beam frequency, an architecture was invented to control frequency changes.
  Unfortunately, first flat screen appears on the market. Thus , the development of analog CRT TV ICs was stopped in TCEC.
