Hi every one
I really need the transistor model of an NMOS in 0.18 um triple well technology for simulation of circuits in hspice. It is due to my M. S. project and I have little time up to my defence session. I have some simulation results in 0.18 um TSMC mixed mode technology, but they are with typical NMOS of this technology. The guidelines to change the transistor models of a typical NMOS to triple well type can help me too.
Thank you for your help.
Unfortunately not. But I think changing NCH is enough, because there are no other physical differences. At least I didn't find any other differences in our model files (from a few years ago), not even in VTH.
SPICE/SPECTRE should calculate the different channel conductance and the corresponding capacitances correctly with the new NCH value. You could try and compare their values.
thanks again erikl. Can you tell me about the range of typical NMOS's NCH in 0.18 um technology? The NCH of NMOS transistor in my technology file is 3.9E+17. Is this difference in NCH value of triple well an typical NMOS (3.2E+17 and 3.9E+17), regular?
