A compact, efficient electrical dual-circuit topology for the representation of transient thermal coupling is presented. Based on controlled sources, the method allows an arbitrary level of complexity to be used for each self and coupled response. Tw

It is shown both experimentally and via MINIMOS simulation that the subthreshold swing S = ∂V G ∂ log 10 I D in a MOSFET may decrease significantly as gate length LG is reduced before increasing catastrophically when LG becomes so short that punc
