A unified SCR model for continuous topology CADA

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 CADA (Computer Aided Design and Analysis) 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 pt´ograms such as SPICE2 and SUPER-SCEPTRE.
