- * 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: 87-06-22
- *
- * 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.
