hi everyone,
i needed some help with MOSFET simulation in orcad capture.I`m trying to simulate a geometric mean circuit using MOSFETS in capture. I downloaded a BSIM v3 .lib file from somewhere and converted it to a .olb file.
The problem is that whenever i use an NMOS from this library,it runs jus fine but whenever i try to use a PMOS trans., pspice displays an error on simulation "Missing Model"...can anyone help me with this? I make sure that i add the .lib file to the design b4 simulation.
i have attached the .lib file as well as the NETLIST generated in both cases
**NETLIST FOR PMOS*** * source TEST V_V5 N247842 0 1Vdc M_Q1 N247893 N247842 0 M12L3P V_V4 N247893 0 2Vdc R_R1 N247893 N250324 1k V_V3 N250324 0 -5Vdc
**NETLIST FOR NMOS** * source TEST V_V5 N247842 0 1Vdc M_Q2 N247893 N247842 0 0 M12L3N V_V4 N247893 0 2Vdc R_R1 N247893 N250324 1k V_V3 N250324 0 -5Vdc
As can be seen from the netlist,PSPICE genrates 4 nodes for NMOS but only 3 for PMOS...i tried looking for a 4th pin in the model but cant find it anyhwre...ANY IDEAS?
