Mj. Kumar et K. Datta, OPTIMUM COLLECTOR WIDTH OF VLSI BIPOLAR-TRANSISTORS FOR MAXIMUM F(MAX) AT HIGH-CURRENT DENSITIES, I.E.E.E. transactions on electron devices, 44(5), 1997, pp. 903-905
A simple analytical model for optimum collector epi-layer thickness W-
epi to maximize f(max) of VLSI bipolar transistors having reach-throug
h collector is reported. Numerical and analytical results for W-epi ar
e compared to verify the validity of our model for the optimum collect
or epi-layer thickness at high current densities.
