BJT models HiCUM (bht)

Hello, 

I came across a Spectre NPN transistor model that uses the hicum bht directive. I am looking for more information on bht level and it also applied to HBTs. I wasn't able to find any information online or the Support website so any information regrading this bht model directive will be appreciated. 

regards

    Did you happen to check the development site for the HICUM (High Current Model)

    www.iee.et.tu-dresden.de/iee/eb/hic_new/hic_intro.html

    An example of the model parameters for for the Spectre bht model (bht is the designation of the HICUM model for spectre) is on page 27 of the 2012 document at:

    www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwj0l-Onuf_-AhWRElkFHT3QAFwQFnoECBkQAQ&url=https%3A%2F%2Fwww.iee.et.tu-dresden.de%2Fiee%2Feb%2Fforsch%2FModels%2Fworkshop0512%2Fcontr_2012%2FSchroter_HICUM_Ovw_slides.pdf&usg=AOvVaw1eAkLrjfmwo9HHoLOzVKwi

    I believe the designation "bht0" is a version of the Level 0 HICUM model. It was first described in the journal article:

    M. Schroter, S. Lehmann, H. Jiang and S. Komarow, "HICUM/Level0 - a simplified compact bipolar transistor model," Proceedings of the Bipolar/BiCMOS Circuits and Technology Meeting, Minneapolis, MN, USA, 2002, pp. 112-115, doi: 10.1109/BIPOL.2002.1042898.

    The model is a simplified version of the full model, known as HICUM/L2. The HICUM/L2 model is described in a companion paper:

    M. Schroter, "HICUM a Scalable Physics-based Compact Bipolar Transistor Model", December 2001, [online] Available: www.iee.et.tu.dresden.de/.../eb.

    This is not my area of expertise, but my curiosity drove me to find out. I hope it is somewhat helpful sidm.

    Shawn

    Thank you very much Shawn and Matthias for the reply and sharing the source of information on BHT. If a device model is using the BHT directive (model abchicum bht type=npn ) is there a way to check from the Spectre model if the device is a HBT (Heterojunction bipolar transistor)?
