Analysis of Anti-JFET for 600V VDMOS and HCI Reliability

MATEC Web of Conferences, 2018
In VDMOS device the anti-JFET concentration has important role for determining the breakdown voltage and on-resistance of the device. Because higher N-drift doping concentration can provide the very best on-resistance of the device but also decrease ...

A model based DC analysis of SiPM breakdown voltages

, 2017
A new method to determine the breakdown voltage of SiPMs is presented. It is backed up by a DC model which describes the breakdown phenomenon by distinct avalanche turn-on ($V_{01}$) and turn off ($V_{10}$) voltages.

STAT3 expression is reduced in cardiac pericytes in HFpEF and its loss reduces cellular adhesion and induces pericyte senescence

FEBS Letters, EarlyView.
Heart failure with preserved ejection fraction (HFpEF) accounts for half of the heart failure cases. It is characterised by microvascular dysfunction, associated with reduced pericyte coverage and diminished STAT3 expression in pericytes. Loss of STAT3 impairs pericyte adhesion, promotes senescence, and activates a pro‐fibrotic gene program.

Statistical inferences for breakdown voltages

IEEE Transactions on Dielectrics and Electrical Insulation, 2000
This paper examines some analysis of breakdown voltages, and gives diagrams and arguments to support re-analysis of the relevant data sets, again using the three parameter Weibull distribution. The paper shows that graphical means provide a useful method for examining the log-likelihood of data, particularly when careful examination of this function is
