BJT Device

The Spectre BJT device is translated as one of the following:

a nonlinear NPN or PNP BJT device
a nonlinear NPN or PNP BJT device with substrate
an NPN device
For information on the BJT model, refer to BJT_Model (Bipolar Transistor Model).

ADS Name	Unit	Default	Spectre Name	Unit	Default
Scale		1	area		1
Region		on	region		fwd
NPN		yes	(see type model parameter)
PNP		no	(see type model parameter)
_M		1	m		1
Parameters not in Spectre Model
Temp ^†	°C	25
Mode		nonlinear
Noise		on
			Parameters not in ADS Model
			trise	°C	0.0
^† Temp = trise + temp ("temp" is an ADS global variable)

The referenced [BJT_Model:Bipolar Transistor Model] is read to determine which device to use:

NPN keyword indicates BJT_NPN or BJT4_NPN
PNP keyword indicates BJT_PNP or BJT4_PNP

If trise is provided, Temp = trise + temp ( temp is an ADS global variable).
