Threshold voltage thermal coefficient (TVTC) is a very important parameter to understand if a Power MOSFET can safely be used in linear zone operation modes. This article explains how TVTC can be calculated taking into account the silicon and gate doping concentrations and the thickness of the gate oxide. It also explains how certain thermal processes, and in particular the band gap narrowing effect caused by the high total doping concentration on the channel, affects TVTC. To validate the complete theoretical study implemented, a comparison between the simulated and the real data is also performed

Abstract
Threshold voltage thermal coefficient (TVTC) is a very important parameter to understand if a Power MOSFET can safely be used in linear zone operation modes. This article explains how TVTC can be calculated taking into account the silicon and gate doping concentrations and the thickness of the gate oxide. It also explains how certain thermal processes, and in particular the band gap narrowing effect caused by the high total doping concentration on the channel, affects TVTC. To validate the complete theoretical study implemented, a comparison between the simulated and the real data is also performedFile in questo prodotto:
