Before diving into the details, some of the terms used in this tutorial are defined here. A simulation program with integrated circuit emphasis (SPICE) is an analog circuit-solving technique that was developed at Berkeley. Even in the digital world, it is still widely used in power electronics and is now combined in mixed digital analog simulations together with other more recent hardware description languages such as VHDL-AMS. Each software constitutes an electronic design automation (EDA), which in some cases combines simulation and PCB board design. While Part I of this series focused on NTC thermistors, this part of the series highlights Vishay’s PTC thermistors and RTDs (both positive temperature coefficient) with their electronic models. PTC thermistors are shown in their typical application function of overcurrent protection, and RTDs are showcased in temperature-sensing and detection applications, similar to what was demonstrated with NTC in Part I.
