LTSPICE KT90 directive

Hello everyone

Being unable to create myself the HT90 directive in ultra linear mode.

If anyone could post it here that would be fantastic.

I found this one but only for the pseudo triode mode 😡


* KT90 LTSpice model .subckt
KT90 P G K
Bp PKI = (0.01798272846m) * uramp (V (P, K) * ln (1.0 + (- 0.1903672493) + exp ((0.1218980633) + (0.1218980633) * ((104.4846442) + (27.71095382m) * V (G, K)) * V (G, K) / sqrt ((- 1.365059137) **
2+ (V (P, K) - (- 19.04749222)) ** 2))) / (0.1218980633)) ** (1.412945234)
.ends KT90


Thanks in advance
