13E1 triode model

Shines asked for this.

* 13e1 LTSpice model
.subckt 13e1 P G K
Bp P K I=(0.8275251182m)*uramp(V(P,K)*ln(1.0+(-0.1204832674)+exp((2.106166727)+(2.106166727)*((6.436533383)+(-4.203510176m)*V(G,K))*V(G,K)/sqrt((27.47170015)**2+(V(P,K)-(-4.502700656))**2)))/(2.106166727))**(1.407837967)
.ends 13e1

IF you want to add the capacitance values do it like this.

* 13e1 LTSpice model
.subckt 13e1 P G K
Bp P K I=(0.8275251182m)*uramp(V(P,K)*ln(1.0+(-0.1204832674)+exp((2.106166727)+(2.106166727)*((6.436533383)+(-4.203510176m)*V(G,K))*V(G,K)/sqrt((27.47170015)**2+(V(P,K)-(-4.502700656))**2)))/(2.106166727))**(1.407837967)
Cgk G K 0.00000001P
Cgp G P 0.00000001P
Cpk P K 0.00000001p
.ends 13e1

(of course put in the proper values in)

Thanks Dr D, very appreciated... will see how they compare to the published Ia vs Vg curves on the datasheet...

cheers
