Hi,
I have a transistor amplifier which I need to simulate.
The output transistors will work at a different temperature than the input transistors.
the spice ".temp " directive sets the simulation temperature for the entire schematic.
My question is whether there is a way to set the simulation temperature independently for each transistor in the schematic? (I use mosfets and bipolars)
Can anyone help?
 

To every transistor you can add a parameter DTEMP, the Device TEMPerature difference to the simulation temperature. Default DTEMP=0 .

hi，
it's an old thread, hope you are still here.
if i want to operate this in a PSPICE model, what should i do?
please in details.

thank you so much!!
 

Don't know PSPICE, sorry. Perhaps you can redefine the temperature for every transistor. If 'dtemp' is a defined parameter, try any one of these:

Temp=temp+dtemp
Temp=temp+'dtemp'
Temp='temp'+'dtemp'
Temp='temp+dtemp'
 

problem solved.
it's T_REL_GLOBAL add in the .model sentence.

thanks
 
hello, do u know how to define temperature for different subcircuits in the same schematic for PSPICE?
