i think the description of the model is wrong and should be QpnpMPA c b e pnpMPA_mod area=dev_a
because the gain of the transistor is a bit over 1, and thats like in the measurement data, where the gain is typical about 1.5.
and if i flip the pnpMPA in the test-circuit so that c
is e
and versa vice, the gain is much lower.
i would also like to know, why the different DUT-measurements of the pnpMPA in IHP-Open-PDK-dev/ihp-sg13g2/libs.doc/meas/pnpMPA
are that different. i dont see any differences in the headers of fg_vcb0_d0406_DUT1.mdm .. DUT17.mdm
, its always
TNOM "27"
TEMP "27"
TECHNO "SG13S"
LOT "PQA701"
WAFER "17"
CHIP "d0406"
MODULE "T323_pnpMPA"
so i would think, the data should be more or less the same for all DUTs
the comments section has a specific DUT defined for each of the .mdm files, and these are different:
DEV_NAME "DUT4"
on the pin order, I'm checking internally
thanks a lot!
in the file
IHP-Open-PDK-dev/ihp-sg13g2/libs.tech/ngspice/models/sg13g2_hbt_mod.lib
there is a model:but if i run the netlist-generation of Xschem for
IHP-Open-PDK-dev/ihp-sg13g2/libs.tech/xschem/sg13g2_tests/dc_pnpMPA.sch
it generates:it seems to me that
c
ande
are interchanged somewhere.
