HFET model

  1. Jun 16, 2010 #1
    Good day!

    Please help me with HFET model for Aim-Spice!

    I have a problem with IV modeling...

    VAX
    vds 1 0
    vids 1 100
    A1 100 2 0 Mhemt l=0.3u w=150u
    vgs 2 0
    .MODEL Mhemt PHFET
    +d1=0.03e-6
    +delta=3
    +deltad=4.5e-9
    +di=0.01e-6
    +epsi=1.0841e-10
    +eta=1.4
    +lambda=0.05
    +m=3
    +mu=0.4
    +nmax=2e16
    +rd=0
    +rs=0
    +sigma0=0.03
    +vs=0.8e5
    +vto=0.7

    please find a mistake in listing...

    p.s soory for my english

    Welcome to the PF. What error are you getting? Is it a SPICE compiler error, or a behavioral anomoly?

    As the DI value of current becomes smaller, this effect should not be. How can I make with a decrease in Di current value decreased?
