Yesterday, 17:38FvM replied to a thread diodes vs temperature in Analog Integrated Circuit (IC) Design, Layout and FabricationAs explained in your second link, the temperature dependency of saturation current IS dominates the actual diode current.3 replies | 106 view(s) -
Yesterday, 16:53FvM replied to a thread How to use NTC temperature sensor in production in Elementary Electronic QuestionsIndustry standard NTC used for climate control have about +/- 0.5K tolerance in the positive temperature range and slightly more, e.g. 0.6 - 0.7 in...4 replies | 136 view(s)
