Method and device for improving hot carrier reliability of an LDMOS transistor using drain ring over-drive bias

   
   

In a LDMOS transistor or matrix of transistors, hot carrier degradation effects are reduced by providing a ring drain and providing the ring drain with an overvoltage bias relative to the internal drain(s) of the LDMOS transistors.

In un transistore di LDMOS o in una tabella dei transistori, gli effetti caldi di degradazione dell'elemento portante sono ridotti fornendo uno scolo dell'anello e fornendo allo scolo dell'anello una polarizzazione di sovratensione riguardante il drain(s) interno dei transistori di LDMOS.
