A Unified SCR Model for Continuous Topology CADA

Abstract
The principle of SCR model parameter estimation from device specification sheets [7] is combined with a reduced version of the intrinsic SCR model [2] to provide improved computational efficiency and better simulation of device turn-off dynamics. The small element count makes computer-aided design and analysis (CADA) of circuits containing several SCR's more feasible. The easy to understand intrinsic model and analytical parameter estimation procedure produce a user-oriented model with common topology applicable to popular CADA programs such as SPICE2 and SUPER-SCEPTRE.
