* Library of bipolar transistor model parameters
*
* This is a reduced version of MicroSim's bipolar transistor model library.
*   You are welcome to make as many copies of it as you find convenient.
*
* Release date: 86-06-20
*
* The parameters in this model library were derived from the data sheets for
* each part.  Where specified, the part was characterize using the Parts
* option.  Otherwise, methods used were as follows:
*
*	NE, NC		Normally set to 4
*	BF, ISE, IKF	These are adjusted to give the nominal beta vs.
*			collector current curve.  BF controls the mid-
*			range beta.  ISE/IS controls the low-current
*			roll-off.  IKF controls the high-current rolloff.
*	ISC		Set to ISE.
*	IS, RB, RE, RC	These are adjusted to give the nominal VBE vs.
*			IC and VCE vs. IC curves in saturation.  IS
*			controls the low-current value of VBE.  RB+RE
*			controls the rise of VBE with IC.  RE+RC controls
*			the rise of VCE with IC.  RC is normally set to 0.
*	VAF		Using the voltages specified on the data sheet
*			VAF is set to give the nominal output impedance
*			(RO on the .OP printout) on the data sheet.
*	CJC, CJE	Using the voltages specified on the data sheet
*			CJC and CJE are set to give the nominal input
*			and output capacitances (CPI and CMU on the .OP
*			printout; Cibo and Cobo on the data sheet).
*	TF		Using the voltages and currents specified on the
*			data sheet for FT, TF is adjusted to produce the
*			nominal value of FT on the .OP printout.
*	TR		Using the rise and fall time circuits on the
*			data sheet, TR (and if necessary TF) are adjusted
*			to give a transient analysis which shows the
*			nominal values of the turn-on delay, rise time,
*			storage time, and fall time.
*	KF, AF		These parameters are only set if the data sheet has
*			a spec for noise.  Then, AF is set to 1 and KF
*			is set to produce a total noise at the collector
*			which is greater than the generator noise at the
*			collector by the rated number of decibels.
