.model … njf(…)/pjf(…) parameters, 3f5 names and defaults (jfet.c keyword table; defaults from jfetset.c).

Fields

njf: bool

NJF (true) or PJF.

vto: f64

VTO/VT0: threshold (pinch-off) voltage, default −2.

beta: f64

BETA: transconductance parameter, A/V², default 1e-4.

lambda: f64

LAMBDA: channel-length modulation, 1/V, default 0.

rd: f64

RD: drain ohmic resistance, default 0.

rs: f64

RS: source ohmic resistance, default 0.

cgs: f64

CGS: zero-bias G-S junction capacitance, default 0.

cgd: f64

CGD: zero-bias G-D junction capacitance, default 0.

pb: f64

PB: gate junction potential, default 1.

is: f64

IS: gate junction saturation current, default 1e-14.

fc: f64

FC: forward-bias depletion capacitance coefficient, default 0.5 (limited to 0.95 by JFETtemp).

b: f64

B: doping tail parameter (Sydney University), default 1 — which reduces the drain current to plain Shichman–Hodges.

kf: f64

KF/AF (noise only).

af: f64

nlev: i64

NLEV (ngspice-47 only, default 2): noise equation selector — < 3 channel thermal 4kT·(2/3)|gm|, 3 the GDSNOI-scaled form; for the MOSFETs also the flicker form (0/1/2–3).

gdsnoi: f64

GDSNOI (ngspice-47 only, default 1): channel noise coefficient of NLEV = 3.

tnom: Option<f64>

TNOM in kelvin (the card gives °C).
