Modelling microelectronic devices using VHDL-AMS : applications and comparisons

The VHDL-AMS hardware description language is suitable for analogue and mixed-signal applications. This paper attempts to exploit the rich expressiveness of this language to describe semiconductor devices. A pn-diode model is described with the lumped-charge concept of Linvill where charge transport equations are simplified and no conditional statements are needed. The model is tested with the Advance MS simulator.
